Ha... I have a great one:
Met a guy in 8th grade. Dated him in 9th. Broke up with him because my depression was bringing him down, and he was a great guy, and it was completely unfair to him for all of my problems in the world should tear him down so much. Still loved him with all my heart. Both of us went through many terrible relationships and were there for each other through all of it. He was my best friend, but always told me that he wanted to rekindle that past flame. At some point in time, we agreed that if we were single at 27, we would get married. He was my best friend... ever.....
Anyway, 27th birthday starts coming around the corner, and I get to thinking about him, and how I do love him, and I tell him that I think that I'm at the right place to be the girl he deserves, and we should go ahead rekindle. Things go well.
Here's the f***ing kicker..... Mr. Nice Guy is no f***ing different then a*****e jerk. He cheated on me, dumped me, then married the girl who treated him the worst less than a year later.
So now I'm with a*****e jerk who can admit he's a*****e jerk. At least he's just a*****e jerk in the sense that he's wittier than me, and I'm just not funny anymore
FYI, when it's Mr Nice Guy who does the a*****e Jerk things, it hurts way f***ing more.
