Me and husband separated and he has not called to check on his daughter?

We have a toddler and one on the way. I'm 35 weeks pregnant. Husband decided to move on to someone else and It really left me broken. He would pick fights with me and blame me for everything. I have depression bad. I tried reaching out asked for help with bills and buying things for the new baby. He does not answer none of my text. I have heard from him in almost two weeks. He have not even talk to his daughter. Another female has his attention. What did I do wrong? I know I gained weight maybe he's not attractive to me. But why take it out on our child?
