GUYS: have you ever gotten emotionally attached to a girl you were FWB with?

my best guy friend and i have recently started "casually dating". he has stated multiple times that he does not want a relationship, which is completely fine with me because i don't either. we've hooked up twice, but didn't have . we talked about it, and he said he would to do it with me as long as feelings don't get involved, etc. etc. however, he really likes to cuddle and shows a lot of affection. we still haven't had yet, BUT i'm just curious, is it possible for guys to get emotionally attached after ?
