Im completely heartbroken because of my ex boyfriend?

we broke up 2 months ago... when we broke up he said that he missed me but i rejected him knowing i was okay without him in the same week he said that he is in a relationship and the girl is really pretty my ex bf is no less he is damn cute every other girl is falling for him i realize i love him his girlfriend is older than him and in another school and its pretty obvious that he fakes it because i had some contacts and i asked so people told me the girl is single and my ex and her are just friends .. vacations have started we all are in different places for that and we skype (group convo including my ex) i have this friend shes friends with alot of guys dated alottt of times and prettier than me.. her figure is awesome i see my friend hitting on him and he flirts back :/ that day my friend asked if anyone wanted a flying kiss before she ended the call .. she gave it to another one of our guy friend but no my ex,, after that my ex said that *because of u rachel didnt give me the kiss* it made me feel bad what do i do i know my ex is a jerk but i just cant resist his cute-ness :/ i sound lame but its true im 15 and hes 16 :)
