What a hilarious thread
Yes, it appears her bf is a problem. You don't mind her spending time with her boyfriend do you???
Okay. If i was you i would go out and find some new friends. For you however, seeing how you are reluctant to sacrifice this great and extraordinary friendship i would recommend to from now on go out all three of you, your ex, you and her bf. I'm sure her bf wouldn't mind if you two hang around under his watchful eye and direct supervision. You may even win his respect by asking his permission to do things like change a topic of conversation.
Yes, now that i think of it, this fantastic friendship may yet work out. Good luck!!!
