Exhausted with my feelings

I had met this man and before we got together he would love on me and be so affectionate and thats what drew me to love him more. My past relationships hasn't never been very affectionate. We been together for 7 months now. At the beginning he would love me in public basically couldn't get enough of me. Having sex everyday just about it. Now he barely talks to me, barely touches me, no sex. Its like I feel like I'm going crazy. Like he's loosing interest or talking to someone else. He'll use excuses now we can't be up each others ass anymore. Or something. I just wanna feel loved like I did at the start. Yes I understand you can't be lovey dovey all time but make me feel like u want me again.
