Relationship Help

So, my boyfriend and I have been dating for over a year. We have always had that lovey dovey connection. As of recently, I have been feeling off. I haven't been wanting to do anything romantic. Sometimes I will but other times I won't. People say that I am falling out of love, but I still do love him. I don't want to part with him. He is trying so hard to please me and I just don't know what to do. I have been feeling like, maybe we would be better off breaking up, but it makes me feel empty thinking about that. I don't want to lose him. Any advice on how to mend something like this?
