I've had this friend with benefits for about six months now. We hang out almost every day and, of course, stuff happens, but we can hang out and seem like the best of friends. I'm starting to like him and would possibly like something more to come out of this. He's been introducing me to his friends and family a lot lately. They're all really nice to me and they always say, "Aww, (insert his name here) your girl is so cute" or they just address me as his girl; all of them. I'm assuming I'm the only girl he's brought around for a while because of how they act when meeting me for the first time. I don't know if he likes me, even though he sometimes makes it seem like he does. I also don't know if I should bring up the fact I like, like him up to him or not. I don't know how he's gonna react and I don't want to get rejected..

What should I do? I'm really confused..
