So let's summarize this 17-year old's "relationship": 
 
1. He's 30 years old and is molesting a child (oh, yes you are a child still, Alysia, legally and quite obviously emotionally as well). 
2. He's in jail - a convicted felon. 
3. He's an abuser, of both women and drugs. 
4. He's already gotten one woman pregnant and doesn't support that child - even if it was a one night stand (which we have a only convicted felon's word for) he takes no responsibility for his actions and the consequences of those actions.  
5. He has unprotected sex with Alysia, exposing her to disease and teenage pregnancy, and cheats on her. 
6. He has coerced Alysia into staying with him by threatening suicide - a classic tactic of a controlling abuser. Clue: He hasn't changed. 
7. She thinks that as a "nurturing" person, she can do some good in his life.  
8. He tells her what she wants to hear so she will continue to allow him to use her. 
 
Dr. Phil, thank you for trying to talk some sense into this girl, but I would have like to emphasize the following to truths Alysia: 
 
1. You can't save him. 
2. You can't change him. 
3. He won't change himself because you are wonderful and loving and giving. And it's pretty arrogant to assume that you are so fabulous that he will be cured by your love and "nuturing". No one, not even you, is that good. He WILL take advantage of your wonderfulness, and already has. 
4. Your brain is still growing and you probably won't even realize you are mortal until you are 25. You don't have the ability to discern between infatuation and mature love, any more than a 4 year old has the ability to tell the difference between movies and reality.  
5. You are NOT mature. Mature people deal with reality, not fantasy, know their limitations, and carefully listen to people with more knowledge and experience. You are not doing any of this. 
6. Turning 18 is meaningless in terms of maturing, so don't think that you will be magically all grown up in a few months. 
7. Your mother loves you and doesn't want you to end up beaten, pregnant, diseased and dumped. Hint: she would be one of those people with more knowlege and experience than you. Dr. Phil would be another one. Listen to them. 
8. It CAN happen to you, you ARE fooling yourself, and your judgement in this case is flawed. Drop the loser who is mooching money off of you, endangering your life and health, cheating on you, and using emotional blackmail (suicide threats) to keep you near him so he can use and abuse you more. If you are as mature as you think you are, this would be a no-brainer.  
 
and finally, 
 
9. You are worth so much more than this. Don't be so desperate for a boyfriend that you are willing to settle for such a low-life. Find someone your own age, in the same stage of life as you, who isn't willing to you at risk. Bad boys are bad news - it's time to raise your standards and upgrade to a better class of men.
