Guy trouble!!

I am almost 15 years old and I was dating a older guy, well we had trouble because I was scared he would leave me for a girl named kayla but then instead he left me for one of my BEST FRIENDS!! They did EVERYTHING if you know hat I mean. And now they broke up around a week after they got together. We was only together for 2 weeks but I felt like I didnt want anyone else but him, now we are talking agian and he has been having a lot of problems with friends so he hasnt payed much attention to me. He has canceled on coming and getting me 3 times in the pasat week and its kinda getting agervating. Should I just forget about him and quit talking to him or should I give him a chance to get things worked out with the other people then let him try to work things out with me??? please someone try to help me.....I am SO confused.

forget the mother f**ker. if he leaves you for for somebody else ( and your friend dosnt sound like a good friend by the way ) forget the jerk. he wont respect you and leve you for someone easer than you again ! forget him and move on !

I dont think he or your friend will do you any good.
if hes going to go for your best friend then I think you should forget him.
but I guess if you like him that much you should go for it and give it a try.
