'Ex' means the romantic relationship is over. If both of you do not feel anything for each other romantically but just want to be friends that is fine, but generally it's the young woman or young man that may still have romantic feelings so it is better not to remain friends and move into the future.
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.
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
yes you can be friends with your ex and that depends if you have a strong relationship with him or her after your breakup..if you do have a strong relationship then you guys must be very close to each other.
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.
