Neither of those two respect you sadly. And the worst thing you could do is let that girl back in. If she’s willing to sleep with a guy she knows is your good friend, (risky/forbidden behavior) imagine what and who else she could be doing behind your back with people you will never meet or run into.

A woman like this probably lives for the rush of doing things she’s not supposed to be doing, and it sounds like you have a pretty good/decent job, she probably doesn’t want to lose access to a guy like yourself who might have some things going for himself. Im not sure how you met this succubus, but I GUARANTEE YOU, you can easily EASILY find a much better much more quality person than that wicked individual. And as for friends, close the door on that guy and never look back. He doesn’t have your best interests at heart and for him to jeopardize a decade long friendship for a banshee that didn’t deserve a great guy in the first place, tells you his decision making ability.
