Breaking up with boyfriend

Hi ladies,

My boyfriend and I have been dating for 8 months now. Throughout our eight months together, we’ve had a couple of fights, most of them prompted by problems that I identify in our relationship. He claims that he is happy with our relationship but he hasn’t introduced me to his parents or family. I’ve met his roommates and their significant others but that’s it. His family also isn’t aware that he’s dating me. As far as his family is concerned, he’s still single and is not seeing anyone. Our families are really important to us. He hasn’t met my family because they live out-of-state, but they know we’re together and have expressed interest in meeting him soon. Am I right to be concerned as to why he hasn’t told his family though he told me at our 5 months that he would tell them soon? Recently, we’ve also been having problems with our sex life. We haven’t had sex since August when I came back from an internship. We spent 3 months doing long distance (~1,500 miles apart). He visited me for a weekend when I was away, and I visited him for a day when I was in town for a conference and we talked through the phone every day. Lately it seems like we’re just good friends who see each other once a week or once every week a half. The last time I saw him he didn’t even kiss me hello. I had to initiate all physical contact. I feel like I’m being neglected and I hate it. I’ve already talked to him about how I’m feeling but he says he doesn’t know what he can do differently. When we go out he never offers to pay for me. I used to pay for his stuff but when I noticed he wasn’t offering the same in return, I stopped. I’ve also surprised him with multiple little gifts throughout our relationship but never has he done the same for me. What should I do? Finals are coming up so I don’t want to make any potentially devastating decisions until after finals are over. Please help
