It's a numbers game. Spend enough time with enough people and someone's going to like you. I'm a whale and I've had partners. I was only normal body weight when I met the first one, next few have been after I went over 100 KG and then around 135. Okay last one was a gold digger but the others were when I was poor (which I am again now lol)
Oh and I'm a sarcastic asshole too, so my personality itself is quite an acquired taste too. It does, however, help that I can keep a conversation going regardless of what the topic is or whether I know you.. Especially helps with people who take time to get out of their shells. It's funny because I'm actually an introvert but as long as you don't catch me in recovery mode, you could never tell.
The ADHD also helps though. One of the very few areas where it does.
I do think book clubs are still a thing tho. Maybe you need to move to a bigger town?
