So I just found a pic of my wife's ex on a friends facebook page.... It leads my mind to wonder what she ever saw in him. He's not what I would call her "type"...

Part of me feels angry for some of the stuff he did and part of me is curious as well. Anyone else ever have experiences like this?

For clarification, my wife and I have known each other since we were little kids (literally) but we've both have significant others over the decades... though this is my first (and only) marriage. Her second.
