I need advice

Okay so a little background on my relationship;

I met my boyfriend online and the relationship started out rocky because he lied to me and was still hooking up with his ex and she ended up telling me. I forgave him but I didn't trust him. He kept doing that to me for a few months and I broke things off with him and tried moving on but he begged for me back.

I went back to him and shortly after his brother died and obviously I was there for him through that. He told me that made him love me. That sole thing was what made him realize I was the girl for him.

I moved to a different state to be with him. When we argue he talks crap to me and I talk crap back and his parents heard us argue once I guess and they said we aren't right for each other and he needs to leave me.

When it's good it's great, but i feel like he just isn't getting where I come from when he does certain things or hides shit from me.

Should I leave ?
