Can’t find my community

Been in Charlotte for almost 4 years. Met a nice girl and are about to get married. The only thing I haven’t don’t is found a group of friends. It may be because of my age (42) and that I don’t go out much. I have reached out to online communities but to no avail. Anyone know of any groups I can join. Interested in sports, comic books, movies, music. 49ers and Spurs fan. I also like traveling. I go to the gym a lot, mostly because of my type 1 diabetes. Anyone have a clue where I should start??
