I imagine that age has a lot to do with the answer to this question.

I want my daughter to have boy "friends", not boyfriends! And she does. I'm so glad about that.

I have had many male friends in my life, especially when I was single. Not date type male friends, but just good friends who were only that. We could go places together, do things like eat dinner out, go to the movies, etc, pay our own way, with no expectation other than companionship. All of us were single too, which makes a huge difference. That is healthy, I think. I can understand a wife or husband being jealous over their spouses relationship with someone of the opposite sex. . But since I've been married, things have changed. I still keep in touch with those people by email or phone on occasion, but I appreciate the way that they have stepped back out of respect for my husband. I would want his female friends to do the same thing.
