Haha! This should be fun. But really, not everytime my ex was a douchebag, my ex was a bitch, my ex was a cheat, my ex was a gold digger. Nah, when they do us bad all the good things they were and they did suddenly fly out the window. Point is, there was something we saw in them that made us date them or fall in love with them; there was some good in them, no matter how little.
For some of us, our ex's were actually great and WE were the douchebags.
In any case, say something about your ex.
My (most recent) ex boyfriend had a very high IQ. He came from money yet hustled like a pauper, thus he was $$$. Errr, which in itself was another "nice" thing about him, LOL. He didn't go out or keep late nights like most guys, like he literally hated clubs or bars and seven nights a week you're sure he's home at 7pm. He bought me perfumes, lots of them.
Now it's your turn. Tell us the nice thing(s) about your Ex.
