boyfriend

so i dated this kid last year and he was a little over a year younger than me. he was always nice and sweet but he was too immature. we decided to end things because the things he did were uncalled for and so i decided to go my own way. i got a new boyfriend and sadly i did things i regret doing with him. him and i just ended things a few weeks ago and he’s already got a new girl. (shows how much our relationship meant to him because we dated for a year exactly) now i’m talking to the kid i dated a year ago. he has changed beyond words and all of my friends think that i should be with him. what do you think?
