I'm in a similar situation and all I can say is that it's just hard to make new friends when your older. I'm a little envious of the guys at work bonding and chatting together about their fantasy football league, kids, barbeques, etc.. I have little interest about those things but I've never really had a group of guys to chill with and talk to. They've been working together for 15-20 years so they know each other well.
For a few years I had a couple of guy friends that I could chill with and have a drink after work. But the problem is they rarely stick around - they leave to another job or move to another city.
I told myself that I should be "more social" last year but it's not always easy meeting people. Everybody's just has their own thing going on and there isn't always room for other new friends.
