Your ex-wife is going to tell her everything. Sorry, you lose.

YDI - but not in a bad way. Having them be friendly with each other can help ease tensions between you and the ex.

YDI, not because you shouldn't have introduced them, but because anything negative that they discuss about you, you did. Don't be lame, they won't discuss your lameness. Simple.

YDI since you were probably trying to make your exwife jealous and it backfired.

Carol and Susan part two?

I don't like how you made ex wife into one word, so i'm putting YDI.

Haha, i agree with everyone who mentioned two and a half men.

1- of course you shouldn't have introduced them. 2- Any time you introduce a current girlfriend (who likes you) with an ex (who hates you, most likely) than they are going to talk about it. And more than likely, it is going to end with your current girlfriend liking you a little bit less, or even downright being appalled by the ex'es stories. 3- girls stick together. when your ex says all the bad stuff you did, but neglects to mention what SHE did to provoke any of that, your girlfriend is going to shamelessly believe her. Then when you try to give your side of the story, your girlfriend will call you immature and say to just "let it go", when in reality she is never going to let it go, and hold it against you till the end of time. ======================= 4- why is everybody assuming they are going to have lesbian sex?? That's just wrong. On so many levels. I highly doubt that is going to happen- UNLESS you know that either your ex, or your girlfriend, is or ever was bi-sexual. THEN it is a legit possibility, and you're already screwed. 5- Don't tell her not to go over there, all it will do is push your girlfriend away. Instead, tell her that you think it's a great idea for her to go over there! When she asks why, say that naturally you 2 would have a lot in common, as they both dated you and your standards have stayed the same. Then mention (jokingly, in passing) that if she mentions anything you've done bad, that of course it's just going to be her side of the story, and to feel 100% free to talk to you about anything she said (in a group) to have it resolved. Afterwards (so you don't look like you are bashing her) say "but she's a really good woman, honest. I don't think she'd do something like that." That way your girlfriend will think of YOU as the good guy, and HER as the girl who defied your expectations and betrayed you... instead of the other way around. Get it?

The point of the "Ex" in Ex-wife is that she is no longer your wife. Therefore, you do not need to introduce your girlfriend to her. YDI for introducting them.

You wont have to worry about them sharing secrets if your HONEST with her.
