Wtf

So my gf is talking to her ex on facebook and he told her that he still likes her and they play 20 questions and she asks him how far would you go with a girl and why didn't you ever make out with me and would you have sex before you get married and he told her that she was a good kisser. Wtf do you think she still likes this dude or what? She's been talking with him for like an hour and half now. She just asked him if he would ever pull a move on a taken girl and if he would ever let a girl give him a bj. wtf..

[Fact]

First of all, how do you know that she's talking to her ex on Facebook?

It sounds almost like she's flirting with him again from what you've said, but then again I guess it depends on the context somewhat.

More information needed to make a better judgement?

Sounds like you're screwed, go charm her and save the situation

Well should I confront her about it. She moved and so he lives a long way away but shes going to go back to visit her best friend. She would never cheat on me ik she wouldn't i just dont know what was going through her head when she was saying that.

[Fact]

Like I said before, it depends how you came to know about it?
If you've been snooping around on her Facebook or something, then surely you need to think about why you were doing that in the first place? Surely you must have been suspicious?
Also, don't lull yourself into a false sense of security be thinking "she would never cheat on me" - that makes it even more painful when everything goes wrong.

Perhaps you should talk to her, not so much confront her, about it. If it's bothering you, which is clearly is, then it needs to be talked about. Just bear in mind your circumstances and be careful on how you word the conversation - you don't want to accuse her directly but you also want an answer.

Good luck
