Cheating

[Hannibal]

Yeah she knows my GF, well I turned her down and told her I'll go over when I'm single, however I'm still sexting with her as a joke, is this wrong?

The question should be, "Would my girlfriend think this is wrong?". If so, you probably should be doing it.

If she wouldn't care, then why even have a girlfriend at all? At that point you're just with each-other for that label of bf/gf in my opinion..

I'd advise against this whole situation. It just sounds like a mess waiting to happen. These are the things that end relationships - unless that's what you're after.

Especially if you're in high school still - I promise you word will get around fast.
