I met my best friend in high school. it's been decades now. we've had periods of time where we saw each other daily and other times when we didn't talk to each other at all. 

The friends I spend the most time with now are through my husband. his bestie from college and his wife. his other college friends. Husband is much better at socializing and maintaining friendships. 

I met my husband pretty late in life and we met through online dating. So I guess that counts?
