Basically about a month ago she told me she kissed her best friends cousin (that I know) on a night out one time, and I was like "okay didn't need to know" but I wasn't too bad because it's only a kiss on a night out, it happens blah blah. but i then find out this weekend that they actually made out in her friends house for "around 10 minutes or more" and I was like "well that's a bit bloody different so to a kiss on a night out" and she said "I still considered it a night out" and then she said last night when I wanted to talk a bit more about it asking if it was just a kiss and stuff she said yes and she said no to him (eventually) and I said that was wrong of him to take advantage (because she had just broken up with her ex) she said "no he didn't I don't think, because I wanted it" and that... that's messed me up the biggest so far because I will probably be meeting this guy in the foreseeable future and I have to live with the image in my head like 😅 and it feels like she's basically lied to me, and the way she reacted was to cry and run out outside when all I did was discover the truth and talk in a calm way.
There are also more incidents that bothered me before but this is the most recent and one that bothers me the most right now.
