I think I'm going to confess to my boyfriend that I cheated last night.
Did you cheat because you don't love him?
No. It was nothing like that. I don't even want to talk about it.
You need to talk about it though, if not to me then to him. It's good to be honest with those you care about in your life, especially on something so big.
I can't do it. I don't wanna talk to him about this.
Earlier you said you were thinking about confessing though. So, part of you wants to, and that's what you should do. Being honest with him and letting him know what happened is better than waiting for him to learn about it on his own.
