love hurts

Ever love someone so much that it literally hurts!? December will make a year that me and my man have been together. It has been 7 years since he has been in a real committed relationship. So things are very different. He is used to being on his own and that makes it hard when it comes to my feelings. I love him so much and want him to know but I never tell him because it makes him feel uncomfortable. He feels like I am trying to make him say it back before he is ready. Which I am not I know he cares, he tells me he does but saying I love you is something he can't do atleast not yet.
