Not enough info chica. Good friends, fwbs, dating? How long dating?
Some guys can't control saying stupid crap like that, called "being caught up in the moment". Is think the guy is infatuated with you, or just enjoys hanging out. Have to ask yourself, does this guy truly know you and your heart, will he stick around if you act crazy or sh*t hits the fan?
Dunno why, but they say like/love after hanging out a couple weeks with a chick. Had it happen with a buddy, then a chick who had it happen to her and came running to me to hookup.
