Relationship problems 🙄

I’ve been dating this guy for about a year and a half now. His previous relationship was pretty long. I feel like I’m dealing with the aftermath of that now. From my understanding they both cheated. Everything was okay with us we were pretty transparent about a lot. He’s now incarcerated & I feel like it’s hit the fan. I gave birth to our baby boy about 2 months ago. But since then he’s been accusing me of doing stuff and it’s honestly taking a toll on me. On my mental. I’m literally home with our baby & my 7 year old 24/7. The first week after having our baby I cried almost everyday because I miss this man so much. He asked for my number one day & we’ve been together everyday since. He was literally like my best friend. I feel like he’s changed since he’s been locked up. I can’t even talk to him about things anymore. It’s either a negative response or “I don’t wanna talk about that right now” so when I shut down he automatically goes to me messing with someone else. Annoying.

Anyways, he doesn’t really speak on his ex unless it’s negative emotion or their child. Which I understand given the circumstance. But it bothers me so bad because I feel like if you’re still that angry about it you’re not over it or the relationship. I’ve always been there to listen to whatever was on his mind and give positive feedback when I can. Am I wrong for feeling a way with that? I try to let it ride and play out but it sits on my mind.
