Help please!

Me and my bf have been together over a year and a half. I recently moved off to college (about an hour away). He stayed in our hometown and has a job. I feel like we're growing apart. He gets mad when I go out with my girlfriends just bc he doesn't know them and I think he doesn't trust me.. I never complain when he goes out with his friends. I just feel like I'm finally sorta independent but I still have to watch what I do in order to please him. And when I go out, I do drink but I think he should trust me enough to make good decisions. And I would never cheat bc my dad did and I know what that does to people. Also whenever I come home, me and him argue over the smallest things, but we also have some really good times.  And I feel like I'm way more mature than him..I just don't know what to do. Any advice??
