help!

PLEASE READ!! 
I've been in a relationship for 10 months now and my boyfriend is showing signs of emotional abuse. He isolates me from my friends and family. He controls what I wear and who I hang out with. He is paranoid and I know he doesn't trust me even though he says he does. And he checks my phone on a regular basis. 
We do have good times too. He's a really sweet guy and he treats me like a princess. But he's controlling. I'm tired of waiting for him to fix himself and I don't know if I want to be with him anymore and this has been the hardest decision of my life and I would really like some help.
