Welll my ex moved on and i feel so empty.?

when we started goin out i was so happy. then i started getting paranoid... wondering who he talked to, was with, etc. then i started wonder about a guy i used to truly love. soon i started wonder if all he wanted was ual activity. i drove myself miserable thinking of all the possibilities. i barely knew him it was so soon! i broke up with him over text because i couldnt face him (ik bitchy right). he was really upset for days but i hlped him thru it as his frnd, after all, i never stoped likin him. we settled on "friends with benefits". it was as if we wer goin out just without a label. he would ask me out alot and i wld say no remberin how bad i felt. i havnt seen him in about aweek and he told me that he liked 2 other girls. he said he liked a girl named jenna and a girl named jenn. im jenny. I found their pictures + woah they look just like me.he said hes probably going to go out with jenna. i cant get over him now. i told him and he said he thinks he should give jenna a chance.
