I love my boyfriend to pieces and we have been together for almost 2 years but sometimes I just feel nothing. When we kiss sometimes I feel nothing. As I said, I love him, but I don't always feel butterflies. Sometimes when I express my emotions, he gives me the i don't care attitude. And during sex, he doesn't always do foreplay and he doesn't really put in the effort. Like I am usually the one giving him head or on top. I guess I just don't always feel wanted by him. How can we get the sparks back?
