"Turns out a cheater allways will be a cheater"
Not really though.
When I was 17 I cheated on my GF and never told her, cause I was an idiot and thought its best to leave it at that and never do it again.
1 month later she dumped me for another guy anyways.
Im 30 now and never cheated since then. People can make mistakes and/or change. I was drinking too much alcohol, I was young and wanted to try things etc and that lead to me doing something shitty.
But I learned to be responsible and also realized, I should have told her, even if that meant the realtionship would have been over right away.
