Ex Pictures.

My boyfriend and I got in a fight over some pictures. He had pictures of his ex and him (not sexual), and I asked that he get rid of them. He threw his ass and screamed at me saying his daughter would never get to see what her parents were like together. They've been broken up since she was 3 and we've been together for 3 years. His daughter often gets confused, and thinks they are still together, and always asks why I'm around which hurts my feelings. He gets very friendly with his ex, and I think it leads her in. I don't think he'll cheat, I trust him completely my problem is is I think their behavior towards one another confuses their daughter. I'm all for amicable breakups, but they are either at each others throats or their being all buddy buddy. Should I be upset? His ex talks a lot of shit about me and about our baby to his daughter. She told her daughter that I was the reason their not together anymore and that I stole him. She said SHE was supposed to have a baby, and that he was trying to replace his daughter. He doesn't react much to this because he tries not to fight with her. When they fight she ends up being completely rotten to his daughter. Ugh, it's fucked up all around.
