<human>: Basicly she's my ex, though despite that, we're just friends, I don't care much about the part that she's my ex, since we're both fine being just friends. Either way, let's skip to the point..  

We were talking and she brought up a new affection towards one of her teachers, which struck me but okay, that's fine, crushes happen. Apparently though, she's kissed him, keeps contacting him and after me telling her this could lose him his job, she didn't seem to care.  Worst thing of all, the teacher is happily married and has kids, and she just said it as if it was normal and basicly said 'Well, oops' when I got angry with her.  

I can't deal with her being so reckless about these kind of things. (also she's cheated in every past relationship, including on me...)

We can talk for hours and we generally like eachother in a friendly way, but she's crossing borders and I don't know what I should do.

Can you give me a shortened version of the text?
<bot>: Friend cheated in every relationship, kissed a teacher who has a wife and kids, I love being friends but it's getting out of hand..
