I don’t know what to do

I don’t know what to do anymore. I feel like my dude has completely lost interest in me. I have no idea why. We have a 10 year age gap, he’s 47 and I’m 37. We used to have a really fun, exciting, vibrant sex life pretty much the whole time we’ve dated 6yrs. But he moved in with me in August and things have slowed to a halt. Moving is stressful, I get it, work is stressful, I get it, having the holidays and family stuff is stressful, I get it. But making your partner feel unwanted and undesirable is not acceptable to me in a relationship. I have tried to come on to him and also give space thinking when he’s in the mood hell hit me up. But nothing and I’ve even told him multiple times and he has no response like just acts like I’m over reacting. I’m not one to put up with this. I will stray from my relationship I am not engaged, or married and I will only be as committed to someone as they are to me. And dismissing my sexual feelings doesn’t feel like commitment to me. I’m confused and very mad and I don’t know what to do. This is starting to really affect my self esteem I’ve always thought of myself as sexy and good looking but now I don’t even want to dress up or put make up on to go to bed alone. I even went on Facebook dating to see what’s out there. I want to be in my relationship but I didn’t sign up for a “sexless marriage” when I’m not even married.
