Is it right to go out or like your bff's ex-boyfriend

No. It's simply not right. How would you like it if the table was turned?

How would like your best friend being with your ex-boyfriend? OK, find a new guy to date.

No... Actually, that's really messed up, regardless of who dumped who.

My bffl dated my ex(one that I got serious with) and it was tourment,I'd say why don't we hang out ? Oh sorry hanging out with my new boy.it was aweful
