Where is the love?

Nadia
Hey all!!
I need some help! My boyfriend and I have been together for 3 years, and over the past 4 months he has completely lost interest in our sex life. I have tried to make advances and got pretty well rejected. 
I spoke to him the other day about how I was feeling and asked if he still loves me. He said of course he does, but the actions are saying otherwise. 
Any help!! I feel so worthless and ugly.
