I went to Italy with 4 of my girlfriends. The trip was actually K. Family vacation but invited us and also and our recently deported(back to Scotland) friend L. ( who is also my sis ex but I wasn’t on bad terms with him) our trip was 10 days it was amazing until he last 4 days. K. Started to develop feelings for L. And me and K were sharing a bed with lots of extra room, so K. Invited L. To stay in our bed so we could still all hang out and drink wine together. I went to bed early cuz I was going to do an early hike but our room was boiling so we had to keep the windows open which wasn’t the quietest. I couldn’t really fall asleep. K & L end up drinking 2 bottles of wine and the last to go to bed. Then end up fooling around RIGHT BESIDE ME. Oh and L has a gf back where we live. The bed was shaking , heavy breathing, flapping noises made it the most traumatizing night I’ve ever had. Every time I thought they were done they would start at it again it didn’t end until the last 2 hours before my alarm went off for my run. I texted k. In the morning letting her know I was awake the whole night. I couldn’t look at either of them the rest of the trip. K. And I were really good friends and I couldn’t believe she did that to me. Out of all my friends she would be the last person to ever put me in a position like that. I don’t know if I can get over this. I can’t help but question our friendship. Any advice would help! Please & thank your! Forgive? Forget her? Or move on?
