That would depend on how you both feel and if you want to then that would be up to you but normally when that happens your friend tends to no longer want to be your friend so you might have to choose who matters to you more, your friend or the guy.
Friends
Dont date him your friends will most likely be upset and not want to talk to you unless You talk to her about it
Date their friends.
You should ask your friend first on how she feels if you date him before asking the guy.
if you are still good friends. Than you can tell your ex.
* It's wise for a friend not to date a friends ex boyfriend/girlfriend, but 'ex' means that person is single and can date whomever he/she wishes to date. If you still have feelings for your ex then your friend isn't much of a friend and you should tell them so.
Only with the friends explicit approval Yes it is.
Yes, you can date this person; I see no why reason why not.
They shall e loya; and not talk each other back and not date each others ex!!
Depends on your views of him/her. If your still friends, then you should. If you aren't, then nah.
Sure, but just friends.
i dont think so
