When it comes to the people in our pasts, the decision to keep them there or bring them into our futures can leave us totally perplexed. That's why when you ask most brides or grooms if they'd consider inviting an ex to their wedding, they'll most likely say, "Sure -- if we're good friends."
Ask if they'd mind if their partner invited an ex, and that's a whole different story. For many engaged couples, though, this situation isn't hypothetical but rather one that has become increasingly common, especially for those who maintain friendships or have children with their former partners.
