How can I make friends?

Ashley
It's a weird question....but I've realized that all of my old friends have moved on and I don't have people to hang out with aside from my bf of 3 years. He goes out with his friends and even if I wanted to go out with mine, I wouldn't have anybody to ask! I used to have a bunch of friends, but now I don't and I especially don't have a ~best~ friend. HELP! How do adults make friends??? I always made them at work or school, but I'm out of school and I'm a supervisor over everyone at work!
