Update: So he has told her no contact and they got in a big argument about it. I asked that I get access to all his things so I have proof. He got angry and said, "What do I need a babysitter now?" I told him that at this point I can't trust his word. The worst part about this is that he intends to talk to her again after the baby is born in February. He literally told me this straight out.
I'm just wondering if I work hard at our marriage in these next 5 months, maybe he will have gone through the whole withdrawal process and have lost those feelings for her. Is this just wishful thinking or do u think this will work?
