Me and my ex-gf knew each-other for three years and within those three years we dated on and off, finally she spilled her feelings for me and we started dating in feb on this year, it only lasted 6 months then she broke it off because I wasn’t being true to my words and I wouldn’t change. She told me if I can change myself and become a changed man she’ll take me back. Is it worth the changed and should I wait for her to come back into my life when I’m a changed man? It’ really complicated to explain it all but I just want an answer. What should I do? I’m confused.
