Friends

Sooo I've been seeing this guy that I've been "messing" around with for about 4 years. we started off as friends and then friends with benefits and now I want to be more then "FRIENDS!" He talks or tries to hook up with other women and I get really emotional and I really deep down get jealous lol  (but I act like I'm not in front of him). So I try to do the same and talk to other guys but I just can't it's not the same. Like I'm thinking of him. Geeeezz... 
So tell me should I just move on? Am I wasting my time trying to see where this goes?  Or what?? I'm lost and confused.. 😁 is this story making any type of sense?? Lol
