If like me, when you left the KH, your ENTIRE social network was gone.
How do you meet people of the opposite sex or make new friends, etc?
Clubs, bars? Not unless just looking for hookups.
I like dancing and had started going to dances, made friends and started getting a social network again. Shortly after I at least had friends and people for when I wanted to go dancing.
I also liked theme parks, etc, but could never get my dancing friends to go, so with that I was alone and nobody to join me. But then I found out about events, facebook groups, etc, and after going to a few I made friends and added more to my social circle as well, now I had people to share that interest of mine. Some liked both that and dancing!
So figure out things you really like to do and look into groups or events for those things, also use social media and look into local groups for those as well. As you do things you like and enjoy you'll meet people who share those interests and you'll already have something in common then!
