<human>: Give me the gist of the text in a nutshell

So kind of a long story but I'll do my best to keep it short.

So my best friend [43M] and I [23M] have been close since I moved to North Carolina and became friends at work. At the time, I had a fiancé who has since decided to go in a different direction with her life. The problem is once I moved here, I realized I am no longer very good at making friends, and have become more introverted. Because of this, he has pretty much been my only really close friend since I've been here.

I used to have a lot of friends when I lived in New York and would really like to figure out how to make more friends around here and be social like I used to be. The problem is that I am his only real friend around here too, and he gets horribly insulted any time I try to do anything without him and don't want him hanging out at my house 24/7. I'd like to meet people my own age and make friends through those friends and be the way I used to be, but I feel like his strange attachment to me is stopping that.

Normally if one of my friends got upset like that i'd tell them to grow a pair and be mature. Unfortunately, about a year ago he went from being my coworker to being my boss. So anytime he gets upset with me, it makes for a horribly awkward work situation. With that being said, I've just been appeasing the situation to keep things normal at work, since I love my job and I don't want anything to ruin that.

To say the least, I need some advice. I've been really lonely since my fiancé left me and need to meet new people but I don't feel like I can without ruining my career because he would get pissy. Is there an easy, simple way to go about this without making him mad that I'm just missing, or am I doomed to ruin either my social life or my happiness in my career?
<bot>: I really feel like I spend way to much time with my friend just to appease him and I don't know how to stop without things going badly. If I ever want to find healthy friendships and relationships, I need to fix this
