What should I do?

Pamela
Hi everyone!
I am currently 6 weeks pregnant with baby #2. I have a 6 month old. My children's father and I are in a relationship. They only issue is he also has a 3 year old with another woman. She is absolutely psycho. Our relationship has been so shakey due to her causing all this drama. She still loves him and wants to be with him but he claims he's told her he wants nothing to do with her. I don't believe that he's done with her. He sneaks around when she wants to see his daughter with out just telling me he is hoping over there. Since we've been together he's claimed they've slept together on numerous occasions but he claims it's a lie. I don't know if I should stay with him or just let the relationship to and just co parent. I do love him but my happiness is more important!
