Hurt.

I'm 20, me and my boyfriend we have a great relationship but I don't think he finds me sexually attractive anymore. I have put on Weight..(1stone) since we got together 8 months ago.. I am now 9st 7ibs. 5ft3. I ask him if he notices but says no. It's really starting to bother me and upset me cause he doesn't pay attention to me as much or thing like he used too
