So I have a 4 week old baby and me and my sons dad split when I was 16 weeks pregnant but slept together on and off after. He left me for his ex girlfriend and basically put me through hell my entire pregnancy. He lied about it for months I found out he swore it ended was all over me sleeping with me and then found out he was with her again. He then promised me he wasn't and now I'm 4 weeks post partum just found out again he's with her and she's rubbed it all in my face
I have suffered mentally tremendously whilst pregnant with no support from him and now post partum I have been seeing him regularly again he has been all over me and found this out. I have had a severe breakdown and don't know how I can face him again. Everytime I see him I get worked up and stressed and how badly he's betrayed me and the mental distress he's put me through I don't know how to continue seeing him at my home. He wants to take my baby away but he lives 50 miles away and he's only 4 weeks old and I don't want to be away from him. I am in such difficult situation I have tried being around him however its too much abd my mental health is deteriorating and I'm suffering badly with PPD.
Can anyone give any tips on how to coparent with someone who has completely broken you . I want the best for my son but I can't see him anymore for now anyway. I just don't know where to go from here. I feel like I'm drowning.
