My (24F) boyfriend (24M) told me he got a girl pregnant and he's not going to be with her, or see the kid.

Ok so I know it's a long post, but please read it all the way through before commenting, it helps if you know the whole situation.<br><br>Also, sorry if it's too ramble-y, I'm still getting this all straight in my head.<br><br>So I've been with my boyfriend for 3 years. We live together, we're in therapy together, we're thinking about marriage, the whole shebang. I thought we were happily together, but I guess not. <br><br>The first time we broke up (a year ago), he started dating a girl named Rachel. He told me about her a few times after we got back together. He never told me too much, beyond the fact that she was cute, and nice, but that he knew he'd broken my heart by dating her, so he ended it.<br><br>Well, a week or so ago he gets a call from Rachel. Apparently, she's 4 months pregnant with his kid. Apparently, he has to go see a doctor about getting tested for a few STDs, because that's the only time she was with him. <br><br>He told me a week or so ago that he's going to be a dad, and that whatever happens with us, he needs to make sure it's good for the kid. I left to go back to my parents for a few days. When I got back, I asked him more about the kid, because I figured that's what he wanted. <br><br>I asked if he was going to see the kid and he said no. I asked if he was going to have a relationship with the mother and he said no. I asked if he was going to tell his family and he said no. I asked if he was going to pay child support and he said yes. <br><br>Then I asked why he needs to make sure our relationship is good for a kid he's not going to see or have any relationship with. <br><br>He said the kid would still know about him, and would know that he treated its mother poorly by treating me poorly. <br><br>I told him that if he's going to have a child, he should have a relationship with it. <br><br>Then that led to a long argument about him not wanting to be a father and how it's not fair to me or the kid, and finally ended with him saying he's not going to be a father, he's just going to pay child support. He's not going to sign the birth certificate, he's not going to have legal custody, and he's not going to have a relationship with the kid or its mother. <br><br>I don't know what to do. I don't think I can stay with him knowing that, deep down, he's a dead beat dad who chose me over his own flesh and blood. It makes me sick to my stomach. <br><br>I really need some advice on what to do about this. <br><br>Edit: Thank you all so so much. I really appreciate it. I'm going to go stay with my brother tonight and think about things. He's been acting very strange and I'm starting to wonder if some of the stuff he's told me is actually true.
