Is this a girl code no-no?

Well girls have a diff code than guys. That should be one of them but girls do it all the time. So go ahead but only if youre friend isn't weirded out by it. Or you can be a b*tch like most girls and just do what you feel whenever you want, not considering anyone's feelings... c:

There is no "girl code"

Do what ever you like. You are your own person.

Assess the situation and the people in it and do what you want. Whether it's to keep you or others happy. Figure out which means more to you.

If your friend is okay with it, I'd go ahead, but keep in mind that she may she's fine with it but in a few weeks once you guys are officially a couple she could change her mind! It's a tough situation. Proceed with caution, I'd say.

It's fine as long as your friend truly has no lingering feelings for this said ex. As her friend, it's your job to judge the unsaid part of the conversation and check that she really is okay with it. If everything's fine, go for it and good luck (if it's you, if it's not, good luck to them!).

Ask your friend if she would care. I wouldn't care if my friends date any of my exes, but I know some people actually care about that stuff.

As long as your friend who dated him is okay with it any kind of "code" doesn't matter. You're fine.

just like close guy friends wouldnt date there friends ex, its the same way around except girls are more shady so you never know.
