So I started dating a best friend of 6 years around January. Really high expectations, things moved quick. We moved in together in August and I was totally in love. I think I got a little too comfortable when we moved in together, and a lot of things changed. Since we started dating she had been working a high-stress sales job with a bunch of older men (she was literally the only girl -- the fact that she wanted to be in that environment should have been a red flag early on but oh well). One weekend I left to go to a football game with my family and when I got back she broke up with me. Totally out of the blue. I found out over a month later than she had cheated on me.

The degree to which this has fucked with my head is disgusting. I moved out of our shared place and am just taking a break by moving back with my parents -- I had to leave immediately. I am not in a good head space about it.

I should not have done this but I we are planning to meet up this Friday. There are obviously thousands of things I want to know but I really don't know what would be good for me to find out. How would you guys handle one final conversation with the woman you thought you would marry who went out and fucked her boss one weekend while you were away, and then tried to lie to you about it?

I sort of know, but... could use some encouragement. Thanks.
