I'm asking the same question myself. Although I haven't moved to a new place, all of my friends are married and don't do anything
social. I was in an LTR/engagement for the past three years and didn't really expand my social circle much since she didn't have many friends. So now I have my best friend, who's married w/ kid, to hang out with and that's with his baby.
I'm starting to assume it's beneficial to have a social circle when you are in or out of a relationship. You have the benefits of social proof and support, which is good not only to show a mate but also for your own well-being.
I'd like to join some groups that will allow me to be social with people my age, 33, but I have no idea where to go. I can't stand clubs, so that's out of the question. Also, I'd like to get into a setting where I could be social with groups of women. I think that's where, as a DJ, you can really shine. My problem is I've always had a hardcore "no-women-friends" policy. Maybe it's time to rethink that one?
As far as showing you have a life, have you thought about volunteering? I've been looking into helping in the Special Olympics.
