Exes

Do any of you ever look up your significant other's ex-girlfriends or boyfriends? I just went through about an hour's worth of doing that. I couldn't help it. There was one girl that I was in almost direct competition with. She wasn't my husband girlfriend when we met but they had gone on a couple of dates. Clearly, I married him so I know I don't have anything to worry about. However, I find myself still wanting to look up these other girls. I'm just curious to see what they're doing with their lives. Anyone out there do the same kind of stuff?
