tired of him being 2 faced

No longer my bf but heard him and his 1st bm talking on the phone ( he records his calls and I went through them yeah my fault but I needed to hear it right) where she disrespected me for 33 mins (that was one of many phone calls where this happened) and he said nothing and she threatened to do harm to me and all he said was let's change the subject. then he stated to her he wasn't going to tell his daughter a fucking things (about our baby) while she's telling him her needs to make sure it's his. He wanted me to have this baby begged and now I hear all of this and it isn't the 1st time she's disrespected me and he has said nothing... I'm not sad or anything of that nature I'm mad as hell and wanting to hurt someone. I don't even want him to attend doctor appts or the birth at this point. And I'm only 2 months I'm like just be a fucking man about it all...
