Help me

Susan

My boyfriend doesn't believe me when I say that I'm sexually attracted to him. We had a fight last night because out of this whole year, we've maybe had sex like equivalent to one month's worth. Not that much honestly. I love him and I am sexually attracted to him. When we make love to one another is amazing. But I'm having problems trying to get that umph to do anything. He doesn't feel attractive because I won't do anything to him and I don't know why I haven't. We've had this kind of fight a lot and our relationship of four and a half years is about to end. I don't want it to end. I love him and I'd do anything for him. But I don't know what to do. When we have this fight, it's like for the next week or so things go great but then after I fall off the bandwagon again. I just don't want to lose him. What do I do? I want to change and show him he's an amazing man and he treats me right but I don't want the same thing of like after the two weeks go back to being the same.
