I fear that my ex's partner is going to get in the way of him having a relationship with his child and also me(as friends) during the pregnancy. We were only together for 6 months when I found out I was pregnant and had been doing long distance before then, but things then didn't work out between us and he went back to his home country a few weeks ago when I was 11 weeks pregnant. We left on reasonably good terms, with him saying he wanted to be there for me and the child.
One of the issues was that he missed his ex, even though he left her because she was controlling and jealous. This came out over time and shortly before he went back he admitted he was going to see if they could work things out. I was really worried about this as I knew she'd been jealous of me when she found out we were together and I couldn't see how she would be fine with me being pregnant and him staying in contact, however he reassured me by saying that he would only get back with her if she agreed to be less controlling/jealous and also was fine with him being in contact with me.
However, since he has gone back, he has reached out a few times but his messages have been unlike him, kind of unfriendly and he was funny about how we were in contact, and it gave me the distinct impression that things have gone right back to where they were before. I asked him about it and he said she has taken him back, is fine about the pregnancy but really doesn't like me still. I feel so unsettled and uncomfortable being in contact with him about the pregnancy (when I already feel somewhat abandoned and vulnerable) when I feel like I've got this jealous person who doesn't like me looming over our communications. When he asked about the scan I insisted on a video call simply so I knew who I was talking to.
While I'm upset about the break-up and how everything unravelled, I don't want to exclude him from the pregnancy or his child's life, given that he's shown enthusiasm to be part of it, even at a distance, but I feel so anxious and stressed out every time we speak because it never seems on my terms, and maybe not even on his.
If it's making me feel this stressed out can I cut him out/reduce communication to a minimum? Or do I need to remind him that he should try and manage the situation better if he wants to follow through on his promises? I thought about being patient and maybe things will settle down but he thought this when they were together last time, but it actually got worse.
