You have some very difficult decisions to face. You are the only person who can determine what will work for you. He will have to take the responsibility to support your baby. The first thing you MUST do is consult a lawyer. Can't afford one? Call the Legal aid society in your area, and explain your situation. Next, call the child protection agency ask them for help for your unborn baby. With my first child, I was confronted with a similar situation, except he was married to me. I went home to live with my parents, divorced him, and he ended up in jail for six months for refusing to pay child support for either child. When my son was two years old, I met a wonderful man who married me and adopted my son as his own. He died 10 years later, and I remarried. Looking back, I am so thankful that I had family to help me.

Wow... I'd beat the crap out of them. I'm a dude though, so that's what I'd do if I were a girl.

There is some sound reasons why people who want to live together should marry... I fear that you have discovered one of them. There are others, such as tax breaks and all of that. However you can not go back 4-5 years ago and insist with "no marry - no nookie". The best you can do is strike this situation up as a learning experience and NOT repeat this mistake in future with another man. Now you are faced with a terrible problem, he has made a choice, that choice is to be a man with two mates to breed with, to have kids. He also has picked one to marry (her) and to support. I'm certain that being the dad to two kids is making it hard on him, but he is a low-life scum in my books thus he doesn't get much sympathy from me. I feel that way because although there was no legal marriage you two obviously lived as man and wife, sharing your lives and your bed so he should have taken care not to stray to far from his mate. You will have to accept his choice and pursue legal actions. Its in your right and its not vindictive. He is leaving you in a jam, being a pregnant woman means you will have a difficult timing maintaining a job. Being a mother with a very young baby you will be over worked at home let alone at a job on top of that. For at least 18 years you are going to be doing a lot of work, and he has picked to spend his time with another kid and woman. What legal actions? Some states have something called "palimony" http://www.palimony.com/ (One link, google or search the word palimony to find relevant data in your area). If he leaves then I do not know what your financial situation for the house/apartment, bills, etc you have but that will leave you in a lurch. Then you need to decide if you are going to keep this baby, abort the baby or have it an put it up for adoption. These are your three choices. I can not pick one for you, but you need to weight each for its merits against what you are able to do. Not just financially, but emotionally and physically as well. I can not make that choice for you, but I will say that I would rather the child be born but if you choose otherwise I will not hold it against you. Raising a child is a lot of work for two parents, more for just one parent. If you decide to keep it then you have rights as a mother to sue the father for child-support. Legally he is signing off on some of his rights to be the daddy - if at this late date he opts to marry another woman who get has gotten pregnant then you can sue for custody with full child support. Trust me the other woman will not be amused by all of this. She might be supportive to a point, but she will never really trust him since he has done a dirty once. As for changing his mind. I'm sorry sweetie but that just isn't in the cards. You can not force anyone to love you or stay with you if they do not want too. Yeah its really sucky and yeah he is a shallow, ugly little man for doing this to you. Being two months along you need to consider you and the baby and what is needed to insure your life without him. You need to plan for the future, and you might as well plan without him. Think of it this way, either way he goes he is screwed. If he decides to stay with you he will still have that other child to take care of, child support is a serious issue now days and men can not run away. If he goes with her he is still responsible for your baby And if palimony is in your area, that as well. Further, She will never fully trust him. She will always know that he was living with you and got your pregnant after he got her pregnant. Sure she may think that she is getting the better deal, but when he starts "working late" or "going out with the boys" she will wonder if perhaps he isn't sleeping around with another woman. And that is something else you need to think about. IF he has slept around on you once, what is to say he will not do it again and again? I only lay these things out for you - only you know what is really going on and the details, only you can make choices based on what is going on with you. Again I'm sorry about all of this.
