I feel your pain--and your confusion.
Please, please, please! ...Don't ever assume that marriage is a license to unlimited access!!! -- not to anyone's body! [Husband or wife! --Believe it or not...it's less frequent, but sometimes the female is the unreasonable one, demanding about sex.]
This ("unlimited access") is an unfortunate misconception held by many--and it is also one of the beliefs that holds victims STUCK--unable to recognize an abusive (controlling, manipulative, opportunistic) mindset and protect themselves from it. AND--unfortunately!--it is one of the beliefs I once held.
Marriage is a license to sole access--exclusive!--but not un-limited!!! --Marriage gives legal sharing of finances, too, but does not furnish un-limited cash access...to either partner. [I'm sure you can see where that would go...!]
Re: sex during my marriage: First of all, the abusive behavior occurs in cycles--which means things sometimes are positive and enjoyable in the marriage, too. [The problem is, anxiety and insecurity always looms, because ultimately, control--always slippery, regularly elusive, and patently unrealistic to expect to maintain!--is what the abuser is perpetually scrambling for. Eventually, some event (however unpredictable, however big, however small) threatens his feeling of control and fuels the start of another cycle.]
But in the meantime...during times when the abuser feels comfortable with the status quo, he can actually be very enjoyable company! It is the positive traits of this person that the victim first became (and remains) in love with...so positive times and positive interaction do exist. This was true of my marriage as well.
Yes, we did have some periods of 'normal' sex [mutually enjoyable and consensual]. He did tell me once, however, long into the marriage, that he had only actually 'made love' to me twice throughout all of that. So...even the majority of times that I felt we were genuinely making love--as a couple--his mindset was still that he was...getting his. He just is not capable of genuine, equal sharing and intimacy.
We actually had sex.on a regular and frequent basis. Unfortunately, because of the dynamic I described and the faulty belief I held (marriage=unlimited access)--which, believe me, he was merciless in 'reminding' me of!--more often than not, sex/ sex activity was not consensual. BTW, when I say frequent, I mean that when we first were together, he insisted on three times a day (whether I wanted to or not). On occasion, I did tell him no--and try to assert my point. He became violent--wrestling me down--putting holes in walls--screaming at me, "There is NOTHING redeeming about you--NOTHING!!!" (actually, that quote occurred toward the end of the marriage, but for the same reason)
That's the thing about an abuser: When you stand up to assert your rights--to hold your position--this for him is intolerable, and violence (verbal or physical) escalates. His entire aim is to get you to back off your point--leave him in charge. Besides being demanding in this way--and countless others!--he would resort to the 'sleep-sex violation' (that's my term for it). --The shame and humiliation was unbearable--recollection of it still can be--and as I've said, my parents, who helped me divorce, still know none of this.
--Almost forgot to mention: He also insisted on doing it even when I had a fever! Many times throughout, because of bad health and exhaustion, I literally just did not have the energy to argue. He knew I did not want it, but that was okay--he did not 'escalate,' because he could have his way easily then. He actually was in very good mood during those times! ...Although, he did ask a couple of times if I could 'make a few moaning sounds'--fake like I was enjoying the sex I didn't want, because he was 'having trouble finishing....'
Several years into the marriage (about 7?) and shortly after birth of my third son, I got an order for protection. My concern about the sleep-sex and potential pregnancy--again!--was part of the issue. [Birth control was another issue I did not believe I had right to put limits on--because of how it would limit him, his preferences.]
I did finally get my tubes BURNED!!!--against his wishes and after many (unsuccessful) attempts to persuade him of the reasonableness of these measures. [I was fortunate: I found out I would have coverage for this; many do not.] I have serious health issues which were exacerbated during pregnancy as well--even this fact was not persuasive to him! We reunited after a few months of separation and with some--supposed--agreement for counseling.
KEEP IN MIND: For those who get stuck in abusive relationship dynamics, the victim enters the relationship playing by one set of rules and the abuser enters playing by another set entirely!
Victim's mindset: The victim tries assiduously to make sure things are fair and pleasing for everyone [but believes she has no right to expect the other person to do the same for her].
Abuser's mindset: The abuser tries assiduously to make sure things go according to his expectations [and believes he is entitled to have his way, regardless of outcome to victim--and feels entitled to treat others like crap, if it suits his purpose for the moment].
In a nutshell: The victim enters relationship with an underdeveloped sense of entitlement--while the abuser enters relationship with an over-developed sense of entitlement. Can you just see the dynamic..tipping into cycle....
In a given situation, the abuser will employ whatever tactics are likely to ensure success--alternating tactics, if need be, until he finds 'the one' that works. --This is another reason abusers are at times well-behaved, at other times abominable!, and also find many shades of gray in between. They cover all ground--to extremes. [Remember: Whatever tactic works....] In the meantime, the victim is racking her brain, trying to make sense of the disequillibrium...figuring out whatever action it will take on her part that can help restore a stable harmony.... Nice little trap!
After that big, long spiel (sorry!), I'll tell you this: I know the relief you mentioned--finally being able to sleep, with him now gone! My ex- held varying jobs over the years--sometimes working days, sometimes working nights, sometimes rotating shifts. Basically, I was fair game any time he was off the clock. And yes, he would keep me up well into the middle of the night, arguing and pressing for sex despite my determined (and irritated)--exhausted!--answer no. [And, as stated before, I would wake up after the fact to find out that he 'done me' in my sleep, anyway.]
This was a daily or near-daily occurrence for about the first half of my 14-year marriage. After the first protection order--yes, you heard that right--the actual physical sexual abuse stopped, though the verbal forms of sexual- and other abuse continued. I was under the misconception then that , because the worst of the physical abuse had stopped, he was no longer abusing me (at least not to the extent that I had a right to ask anyone else to help me do anything about it!).
About four years later, he started looking up porn on the Internet and the physical sexual abuse resumed (enter protection order #2). Again, more superficial and temporary attempts at counseling, and we reunited. Five months later, I moved out. I did not file for protection this time, since I knew he would not have ACCESS to my body at all now.
I was finally in a position where I could give myself permission (and have help!) to divorce.
He still abuses, manipulates, and controls interaction with me...but from a distance.
Breathing easier now....
Sorry for the unduly long response. It's just what spilled out. I hope this helps you--and anyone else who reads it. Feel free to respond.
