<human>: (Sorry for bad grammar)

So my girlfriend and I had a conversation some time ago about when you have crossed the line when it comes to cheating, and i told her that i wouldn't be okay if she kissed with another girl, and that I would consider it cheating, she then accepts how i feel and agreed not to kiss with anyone else than me.

After some month we where to a party together and she then asks me if she can kiss with other girls, and i would be okay with it, i then said okay and that she from now on was allowed to kiss with other girls. 

But then i found out she alredy had kissed one of her friends before i said it was okay, and she is saying it isn't cheating because she isn't a lesbian, and i later on gave her permission.

Can you condense the text into three sentences or less?
<bot>: i told her i didn't want her to kiss another girl, she then did it and later i gave her permission
