My boyfrinds bestfriend

You broke up with your boyfriend. He is your ex and you don't have to tell him ****. That's what being an ex is all about. He doesn't get the privilege of that information any more.

As for the other guy, maybe reassess your life a bit, if you are having sex because of coercion. Even if you had a good time or think everything is wonderful, the bottom line is, you need to take more responsibility for and control of your sex life.

And maybe hang around with people who aren't incarcerated or are best pals with folks who are.

You were broken up when you had sex with that other guy.

Now you are with this new guy, right?

I hope you did not use this other man just to get back at your BF. That would not be fair to anyone.

You have moved on without your ex. You don't need to explain anything to him. Stay away from your ex.
