What do you think?

So lately I’ve been getting this vibe that my boyfriend wants to be with his ex who they share a daughter with. I know I have been extremely insecure and have a lot of mood swings. I’m 15 weeks pregnant. But I’ve seen some shady stuff going on. So not too long we had a conversation and I thought he was really leaving the house. When he got home we talked again and I was crying so much and telling him that I don’t want to lose him and I want to try my best to change, but now I’m scared he just stayed because I was crying to him that I don’t want to lose him…
