It is never okay to date your friend's ex-boyfriend.
move on no girl would go out with her friends ex unless her friend said it was ok
Why not, if you remain friends.
Only with the friends explicit approval Yes it is.
Well it depends, if you are still friends with your ex, it would probably be ok. But enemies I would not. (Unless you really actually love him).
You can still be friends with your friend, but just try to remember to not get to close to your ex, and remember that your ex may be trying to make you jealous (it is possible that they aren't though). It is OK to be friends with an ex.
I'll go ahead and say it's ok. Unless your trying to make your friend jelous or something, you should be friends with him if you'd like. If she gets mad...she's not really a good friend. Is she?
You had a courtesy to ask your best friend if you could go out with her ex and since she has told you she doesn't mind then feel free to go out with him. 'Ex' means the person is single.
It depends on how long it has been since they broke up and if your not sure then you should go ask your friend about it and if your friend says it's ok but then is mad at you later it's not your fault your friend is the one who said it was ok anyway so yeah.
if its ok with her but you gotta remember your not a couple any more
The one mistake you made dating your best friends ex is not discussing it with them first to see if they would be OK with the idea. Best friends should last forever and should never let a guy/girl come between them. It's time for you to communicate in private to your best friend that you made a mistake by dating their ex and wanted to let them know and if it was OK by them. If not then stop dating the ex.
Yes,that is ok
