Pregnant-Boyfriend Cheating-Maybe this is a dumb post

Hi

So maybe about 2 months ago, my boyfriend cheated on me with some girl he works with. When I caught him, the usual shit you hear, “she means nothing to me, it was just sex, you are my girlfriend... I care about you and the baby.. etc”

Ok.. so I left him. And he begged and begged for me to come back. A lot of me didn’t want to, but I live alone here in New York, without my family, and I want my baby to have a beautiful life, so I went back to him.

Come to find out, she is still texting him and he responds. So, me, being quite crazy, confronted her. Basically, she told me that a baby doesn’t matter and she doesn’t feel bad about any of it. She called me a bitch, and told me to fuck off. And she continues to throw herself at him.

I don’t even know how to explain what I am feeling. They have not slept together AGAIN, but clearly they are still talking. They work together. I don’t want to be home with a new baby wondering where he is.

This might make me sound so stupid. But what do I do? No one knows about this. So I have not asked for advice.

Also, not to focus on this: but what kind of person continues to text a man with a baby on the way? I mean, also what kind of woman am I if I stay with him... but i would never do that to someone else.
