BF, not FWB

My boyfriend and I started as FWB, and he persuaded a relationship, only now after a year though said he was my BF. He kept saying we were just sex buddies, but then talk about how he loves me, wants to many me, then go back to saying it's "nothing serious". It confused me so much I broke things off, but a few months later, I took him back. He said he would change, and he did, kinda. We still seem to only meet for sex, and he's always asking me to fuck other guys/girls, even my own roommates! I always tell him I'm uncomfortable with it but he still brings it up. I feel like we sound just be FWB again, or have a serious talk or something. I keep trying and trying, and the final straw was today, Valentine's Day. He lives less than 15 mins away, and couldn't even MAIL me something! All I got was a nude and "happy Valentine's Day". I know he cares for me, but it's like he doesn't realize we are dating. He works and goes to school, but he has a bunch of free time as he doesn't have class for 3 days, and will only come over if I'm alone, if I have a roommate home, he doesn't want them to see him. Also, he says he has planned a proposal to me, well I'm not going to marry a guy who hasn't taken me out and won't even meet my roommates.
