Another relationship dilemma.

I'm currently 18. I've been in a relationship with a man for 1.5 years now and we've had a bumpy ride. There is an age difference of 6 years but I really don't believe that is the exact problem. I feel like he gets so disoriented with college and his new friends that he forgets to give me some attention. I'm not very pushy or naggy. But I wonder if I should? We've had various "breaks" and "break ups" but when should there be a limit? Sometimes I feel like he doesn't really try. But he tells me he does. I love him, I do. That is what's keeping me here. But what do you think I should do?

Opinions/comments appreciated. (:
