I've started seeing someone and (as you do) I googled his name.
It came up with this "bad boy report" from about 10 years ago - it's basically a girl saying she got chatted to him online, he told her he loved her, they sexted etc and then she found out he had a girlfriend.
I questioned him and he said it's from 10 years ago, he was stupid and it was a mistake.
Would it bother you? Or would you forget about it?
