Suuure did.

I confessed to the guy and we went out that night and ended up sleeping together. The next day he said he wasn't interested in me. So I went out a few days later and slept with his best friend. When his best friend dropped me off at work the next day (all 3 of us worked at a mortuary together) the guy I confessed to flipped out and started yelling at his friend and kicked a dent in his car, then he weirdly stalked me all morning and was giving off crazy vibes. His best friend (the one I slept with) was super nice to me though and was on my side the entire time.
So I knew he was the kind of guy worth keeping around. 3 years later, we're engaged. (▰˘◡˘▰)
