I didn’t plan for feelings to develop, but they did.Is it ever okay to date a friend’s ex? And how do I tell her and our friend group, without ruining everything?Grandma Gail: I would certainly hope a little time elapsed between the break and your going out.

And then I would definitely say to my friend, ‘Would it bother you?’Kim: Don’t just say, ‘By the way, we’re dating.’Grandma Gail: Right.You might end up not being that friendly with her anymore.

If you really think there’s really a chance of a serious relationship, I would go for it, but I would tell the friend, ‘You know, I’m just gonna tell you right up front.’ If she hasn’t moved on, that could be an issue.But, you know, I still think you have to try it if you really feel that strongly about the young person.Kim: I feel like there are so many men and women in the whole world, why do you have to go for your friend’s ex?Grandma Gail: Because sometimes that’s the person you’re closest to.

It’s like very often when people get divorced, they end up going with friends who they were friendly with who also got divorced.Because you’re more comfortable with those people.Kim: If it was my friend and they said they wanted to go out with my ex, I would not want to be friends with the girl anymore.

Grandma Gail: Oh, really, okay.Kim:...
