I have this guy i like guy but my bff is his ex. What do ido?

Question

and me and her are really tight

Answer 1

If you and you BFF are really tight then you should be able to ask her if she minds if you go out with her ex. Her answer will tell you what you should do.

also, if you know she is the jealous type then you know your answer allready and shouldn't risk the BFF status......
