What should I do?

[Credos]

So me and my LTR gf went out yesterday with a few of her friends, we had a lot of fun etc. I'm making some jokes with the guys nothing special. Teasing her once and a while, but nothing really bad cause she's teasing me back...
Anyway on the way back on the train, where we had a food fight etc ... One of the guys (friend A) spits water on the other one (friend b) ... And she gets back friend A for friend B cause he didn't do it herself .
Now I'm saying to him: you just not gonna let her get away with that ...

She gets kinda pissed at me cause I'm taking his side lol... (women right?) and in her anger she says: I'll cheat on you...
(friend A gets it right away that that hit the wrong spot in me and tells me she doesn't mean it and wouldn't do that, but hes just being her friend right...)

I'm thinking like: WTF is that for a reaction... I said a bit later that I really didn't like it that she said that... later when we got off the train she's saying: sorry, i didn't mean that... I'm really sorry blablabla... But its stuck in my head. I really don't know what to do about this, even if she was kidding...(how can I know that she won't cheat one me? I can't... thats just thrust, but how can I thrust her if she says she will cheat on me... LoL) I don't wanna be a *ss at her by nagging about it , but thats not really things you say to your boyfriend right?

Any suggestions about What I should do?

Let it blow right off your shoulder, shes not gonna cheat like she said "it was a joke" and thats all it was. It seems like you haev some trust issues man but just let it blow off.

But if you wanna show her it affected you without negging, be a bit distant for a while, not wanting to get intimate, say you have other things to do, that sort of stuff, until she brings it up herself, then you can have a conversation about it. But in my opinion you shouldn't do anything soon as she sees it affected you her views of you might change, jealousy (trust issues) is a inner flaw of having no self confidence. Some girls dont like that in a guy, they want a guy with tons of confidence and seemingly having no flaws, so it could effect your relationship letting her know its affecting you this much.
