Mhairi Gaelic version of Mary (dad's mum who passed when he was young) or Mercedes after Mercedes McCambridges who was the voice of the demon in The Exorcist. I dunno what my mum was trying to say about me.

Just be honest. People go on a journey with their sexuality and gender. It's better to be honest than lie.

Yes your bf cheating is a horrible thing to do but outing someone is not the way to go. You know it's dangerous for them to be outed and you still want to do it because you're hurt. Just walk away and be done with it instead like an adult and not some bratty kid. No you wouldn't make them do anything to themself and you say you wouldn't care but it will weigh on you and is it really worth it?
