Sometimes if the girl got broken up with she may still have feelings for him ad get jelous.
Or she thinks he is a real jerk and doesn't want you to get hurt.
If you already broke up then i cant see why not just be sensitive.
Date their friends.
Friends
Only with the friends explicit approval Yes it is.
Yes, you can date this person; I see no why reason why not.
get that girl to talk to some ex's
i dont think so
It is never okay to date your friend's ex-boyfriend.
appologise and arrange a date
Well I see my ex everyday and were good friends. And I don't want to date him again were good friends though, and we can talk, sometimes it just means you've moved on and are ready to be friends
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.
Friends are friends and if you like this girl then it does not matter if this girl is an ex of your other friend, but be sure to let your other friend know you are seeing this girl and why. When you are with the ex girl try not to discuss the relationship she had with the other friend and just enjoy each other.
