No it's not bad, people break up and move on. I am not even friends with my ex boyfriends, I don't see the point. I do think though that certain ex's will hold a place in your heart, like first loves but either way I would find it annoying if my partner treated their ex different than other people because at the end of the day, they're not your partner anymore. I don't keep in contact with people that have hurt me, I don't have time for that, nor should anyone, people who care about you, should not hurt you.

Not at all, there was a reason why they are your "ex". It's the adult thing to recognize them when out and about, say hello and then move on. The sweetest revenge is to find someone better than the ex and "run" into them...
