u sound like a really nice guy and the only thing u did wrong was chooseing the gurl to fall in love with cause i know this type of gurl cause i used to be like her i'm going to be straight with u this gurl only dated u cause u were older and her friends thought it was kool, and she cares what her friends think about her. when u broke up with her it made her look bad so she thought if she hooked back up with u then dump you would make her so popular with her friends, but watch one day she going to realize that u were a great guy and she missed her chance

p.s just because this gurl broke ur doesn't mean every gurl will so keep ur heart open and you'll find the gurl that will make u happy
