I didn't sleep with him, but I did let him get to my heart again. I swear, I am so stupid. My birthday was yesterday, well my stbx (soon to be ex) came home Monday evening really drunk and I helped him to bed. During the help that night and all morning yesterday he was so sweet. I want us to try to work it out, I will go to counseling if thats what you want, I believe that we can make it. So it is my birthday now, I call and set up the appointment with a counselor for next week. My husband calls me at work to see what it is exactly that I would like for dinner, so we decide that. The day goes on, I'm 40, I'm happy, it's my birthday. He comes home from work, still happy and begins to cook. Well our 10 year old is home and talking to him, then our 19 year old who lives with us comes home with her boyfriend and their new baby ... something happens, don't ask me what. I go into the kitchen when dinner is almost ready and my husband calls my 19 yr old in to see if she will finish the chicken as he has to go. I'm confused, I ask, "where are you going?" He has made a plate for his girlfriend, of my birthday dinner, and is going to take it to her at work, but will be back in about an hour or so. My heart sank to the floor and slithered off under the refrigerator never to be seen again. I felt so stupid and embarrassed for believing his lies all day. I know I don't deserve to be treated this way, but every part of my heart tells me that I should try to save my marriage. The vows do say for better or for worse.  
I wish I had the money because if I did, I would see a therapist weekly if not more and file for divorce tomorrow. I can't go on like this, he is slowly and painfully killing my heart and he doesn't even give a crap.  
Oh god, please let me win the lottery tonight ... I will gladly give him half the money just to get him out of my life once and for all and get on with living for myself and my kids.  
The game playing isn't over for him, and he knows that your heart is still there for the taking. Why did he come to you when he was"really drunk" and not to his GF? Maybe because he knows that she won't put up with that kind of behaviour and you will?
I know that you believe in "for better...or worse" but it takes two to make a marriage. Its work, hard work sometimes, it doesn't seem that his is willing to put the work into it, but he likes to keep you dangling...that is abusive for you to endure.
Its hard to walk away from history, the history you have together..but making a plate up and delivering it to his "girlfriend" makes it plain that his heart is with her not you. I've been divorced three times, I believe in marriage,,I just make terrible choices about who to share my life with. I know the pain your feeling, sometimes you need life to hit you up the side of the head before it sinks in that he is moving on and your stuck in "wishing it would work".
Wishing won't make it so...
Please try to move on, disassociate from the emotional side with him as much as you can, until you get thru the stages of seperation and divorce and all the emotions that go with it, you will forever be stuck in the past and wasting time that you could be sharing with someone who will love you the way that you deserve! Good luck ~Red
