Friends with an old flame?

It's so crazy. I was friends with this guy from the time I was about 10. In high school, we got strangely flirty. We had some moments, but nothing ever came of it, although we have stayed friendly all this time (I think nothing happened because of religious reasons). Fast forward three years. I'm married, my daughter was cooking in my tummy, and my poor husband is a transplant to our area  who works 60+ hours a week. He was complaining about not having any guy friends. So, I call my friend, Matt. A few months later, he and my husband are good friends, and Matt is planning on proposing to his girlfriend. It's just funny how life changes. I don't have lingering feelings for Matt, more or less just an appreciation that we can be friends, and especially that he's such a great friend to my husband. 
Any similar experiences?
