For context, the man who is now my sister's husband was actually supposed to be my husband once upon a time. My sister (27F), I'll call her Melissa, hooked up with my fiance Lucas (29M), on the day of my engagement. Lucas and I had been together since college and he proposed to me after almost five years of being together. He'd thrown a party for us, to surprise me on the night of our engagement and I still remember feeling like I was on top of the world until around ten pm, when I decided to go out into the backyard for a better reception and caught my sister all over Lucas there. They were making out so passionately, that for the first couple of seconds, they didn't even notice me standing there with my mouth wide open. I couldn't believe that he was doing this to me after almost five years of togetherness and on the night of our engagement, no less. When they finally did take note of me, they broke apart instantly but it was too late. I made a run for it, got into my car, and drove as fast as I could to the nearest hotel that I could find. I was hyperventilating because I was so shocked at what I had witnessed. I was somehow trying to process it and was willing it to be untrue but then I received a text from Melissa, saying that she was sorry but she was in love with Lucas and apparently, this had been going on for a really long time now. I was in the hotel room when I received that text and I broke down like never before. After Melissa, Lucas texted me pretty much the same thing and said that he had only proposed because he felt that if he committed to me, then he would be able to push Melissa out of his head.
