My relationship is going nowhere, we have no bond? Please help :(?

I have been dating my boyfriend for practically 5 months. In the beginning months of courtship, I never knew if he liked me. Yet he kept seeing me. He eventually kissed me, but it took him over a month to try and hold my hand or touch me at all. We met at my local community college. Sure enough, he decides to ask me to be his girlfriend. He made it facebook official before I did, but the fact is... we have not become closer since the courtship phase. He does not reveal feelings for me, ever. Compliments are few and far between and always have been. Sex is great, but emotional connection is absent on his side and I am forced to pretend like I have none. Some days he would skip so much as a goodnight after work. I know he works and all but we live down the street from each other and he rarely sees me. I don't know why he has committed to me to make me feel neglected. Lately he has been snippy with me, which is new. I asked him if he even really wanted to be with me and he said yes, and talked to me every day of that week. It doesn't help his dad still has a curfew of 11 on him at 20... I don't want to break up with him... yet I have never told him how sad and alone I feel. I'm afraid he'll walk away...
