Boyfriend gave up on relationship, but doesn't want to break up with me?

My boyfriend and I have been dating for about 6 1/2 months. The first 5 were like an emotional rollercoaster ride. He had a hard time trusting me because of a girl cheating on him about 10 years ago. Alot of his allegations came from me being independent. For example: I would go to the mall on my day off, he would call me, my phone's battery died, so I miss the call, but call him back when I get home...But then an argument errupts and he would falsely accuse me of sleeping with someone else. So imagine this behavior at least one a week. It really felt like I couldn't do anything without being accused. About 5 months into the relationship, he begins to trust me (but only because I pretty much halted alot of things in my life). I started noticing that he is becoming more independent. Hanging out with friends at the bar, fishing trips, etc. Doing the exact things that I got punished for in the beginning, which actually bothers me alot. But now fast forward to this week. We had a mild argument recently about how he doesn't feel the relationship anymore and that he can't have his space, he wants me to go do my own thing now...But you have to understand the emotional abuse this has put me in...So, he tells me that he doesn't feel excited anymore, has given up on trying to fix it, BUT he doesn't want to breakup with me...huh? This is where my confusion comes in...Why would he not enjoy being with me anymore but says he doesn't want to break up? Its this some kind of game?
