Yes. Not proud. No excuse, but I was better mates with him than her. He said they'd split up for good, she said they were on a break. They got back together a week later.
I guess, she wasn't too important to me but we were friends. First I was his girlfriend, then a few months later he was with her and I was his side girl. Always did kinda resent her for dating him just after me. And no, we're not still friends.
