Can our relationship be saved?

My boyfriend and I have been together for almost 3 years. Although back in the Winter, we split up for 5 months. We got back together in the Spring and things were great at first. Now last night he texts me and says he wishes things were like when we got back together. He said something doesn’t feel right in the relationship. I agree that something doesn’t feel right. I told him I have been the same as always and that he is the one pulling away from me by spending a lot of time with his friends and only seeing me once a week. I told him we need to start communicating better and try to make more time for each other. He said I never want to go out and do things with him, but that’s the farthest thing from true. There are a lot of things we could go out and do together that I would love to. I said that whenever I try to make plans with him he’s always with his friends. We’ve been through so much to give up now. I told him this is something that can probably be fixed if we just try, but he still seems unsure. I really want to make this work. I don’t think I could deal with losing him a second time.
