If you could undo one mistake in your life, what would it be?

Mine would be to NOT go out partying on the night of October 24th 2014. I was in a new relationship (2 months) and decided to go out with my friends without my BF. As the night unravelled I got pretty drunk and was acting pretty hyper. We were bar hopping and I ran into a guy I had a thing with a while back. So we got to talking and before I knew it we were at his apartment. I was really drunk and don't really remember well but I know for sure nothing happened, besides we weren't alone, there was another couple there and we were just drinking/talking. Anyways, one of my few brain cells that were still working made me realize that this situation wasn't right, so I got my bag and stormed outside where I called my BF so he could come and pick me up, he did and as you can imagine was pretty pissed at me. Next day we talked and he forgave me, so we carried on with our relationship for two more wonderful years and nothing like that ever happened again. But he was never able to completely put it behind him, when we got in to fights he would bring it up and it became the source of our problems. We recently broke up for good and I just can't help but feel that that night doomed our relationship. I didn't cheat but he couldn't fully trust me again. So that is the one mistake I would undo. And maybe we would still be together.

Sorry for the long story, let me hear yours.
