Ok to most of you this will sound pretty ****ed up. I broke up with my girlfriend a few months ago, we were only together a few months. Words don't do justice of how beauiful she is, I'm still head over heals in love. She was the best friend I have ever had as well.
But the problem is that I'm 18 and she is only 15. My dad told me he was disgusted with me and my mum hated her. Once I joined university I lost control, I cheated on her and did some bad stuff. My "mates" persuaded me to end things with her.
But it was the biggest mistake of my life, I love her, but it can never work because of the age... and I can move on. What should I do?

Look from my point of view this is what happened with me and my boyfriend ! He is 18 and I am 15, I love him ! And I found out he cheated on me, but I don't know who with ! He never told me about it, I found out in an email on Facebook ! I know that if you still love her ! Don't let her go because once she is gone, she is never coming back !

Move on, stop contact with her, don't answer any emails, don't follow her on face book and date and move on

Age is just a number... really if you loved her age and your friends shouldve never mattered at all. When I met my current fiancée I was 15.. he was 17 now I'm 17 he's 19 and his friends did the same as yours. But he loved me both of our families were concerned with our ages but we moved on and stayed together. Honestly you can't move on cause you know you hurt in a way you'll never understand but what I can tell you is.. you may be able to get her back as a friend if you slowly re-build your friendship and mabye in the future when your "age" doesn't matter to you both of you will let the past go and stay together.
Good luck
