So here it is. SO invited me to come with her in college friends reunion sleepover in a hotel. Beforehand, I declined after I knew that her ex is coming and yet she still insisted it and i came. We had drinks, watched netflix and had fun that night. Then time to sleep came 3 of us sleep together in 1 bed as there no space for her to sleep in, part of get offended but i tried to be calm. The next morning I wake up and notice-that the 2 of them were gone, I find them in the balcony (just the 2 of them). After that, I burst out and really feel bad about it. I walk out the room with tears in my eyes. So am I totally overacting about it?
