HELPPP!! okay so my boyfriend of 5 months thinks that i don't actually want him, and i only want the idea of having a boyfriend, which is sooooo inaccurate but he doesnt understand that. i truly love him a lot and so does he, but he doesn't understand it. It's both our first time in a serious relationship and we're both pretty cold people except when we're together, so what do you think is making him think that i don't want him? and how can i prove him wrong. we decided to be just friends and i'm only agreeing because it's better off than not having him in my life at all.
