Yes,they are fair game.If a woman splits up from a guy they can date who they want and if it is a friend of an ex they have no say.

I don't see why not. Ex means no more.

There's a saying here, that more or less translates to "who leaves for Rome loses the chair".

Sure, I'm not going to organize dinners and hangouts all together esp. if they're not in talking terms or anyway they're awkward around one another, but aside from that they don't have much to complain about.

If you're asking this for a friend, just give them permission. 🤔

Sure they aren’t with them any longer

Yes, I think so.

Not a good idea.

I'm so sick of questions by that Riley chick

If you're into excitement yeah lol

Is it okay to wear your friend's used underwear?

It’s a really bad idea. Feelings involving “exes” are usually very complicated. Not something to even consider unless you don’t really value the friendship and would be okay with possibly losing it.

Only for the purposes of revenge, or maybe if you're bored, or possibly if they're really hot. Other than that, it's a no.
