Should I just end it?

My boyfriend and I have been together for a few months. When we first started talking he'd go out with all of his roommates and I was totally fine with it but I recently found out that one of those times they went to a strip club, all got lap dances etc which im completely not okay with & I hate that he hid it from me. I feel like he hides lots of things and it doesn't help that he's in a fraternity. Tonight we had plans to go out together but he completely ruined them to just go to the club with his friends and didn't even invite me. I hate that I'm always worried that he'll cheat on me & I hate even having to be suspicious about why he never takes me =\ should I just end it before it could actually hurt me more?
