Im not sure what i should do help?

So my boyfriend is 20 and I am 18 we have been together for a year but lately it seems like all he wants to do is garb on me touch me try to have etc. and it's really annoying. I have also found that he watches on a DAILY basis even when our life is going good. he started watching anime and has the sites bookmarked on his computer. Even when we have he can't seem to keep it going, its almost pointless for me. It is about 5 minutes at the MOST. I told him last night i didn't wanna have anymore he can stick to his and now he wants to think about our relationship. does this prove he only cares about ?
