I need major marriage help!!!!?

Ok, i've been with my husband now for 2 and a half years and lately i've been feeling a little disconnected from him. we haven't had for 3+ weeks and i know he isn't cheating on me. i'm 110% positive he isn't so don't reply if that's going to be your answer. He says he doesn't see anything wrong with our relationship and that he had so much before we got together that it's like nothing to him now and he doesn't crave for it. well that kinda stinks for me cause we only have when he feels like it. i feel like a guy!!! and he uses it against me if we are in a disagreement he says we cant have cause i was being a *****. or that something was my fault. we don't snuggle anymore the only time we actually touch is before he goes to work in the morning and we peck kiss. no tongue no intimacy no nothing. what is going on here. again i know for a fact he isn't cheating and he says he doesn't see anything wrong with our relationship and he says he still loves me.... what's going one? what can i do?
