The best part about introducing your friends to each other is that then they can hang out with each other without you having to do anything at all! I definitely have some close friends I expect to see multiple times per week. Others I'm perfectly happy to see once per month. Others who have moved away and I won't see until I visit their city.

Friends and community are not a zero-sum game. The more interconnected and inter-dependent people are, the more likely that everyone is going to have deep and meaningful relationships.

I used to feel much more like you when I was regularly hanging out with friends almost exclusively 1:1. I thought I was doing that because I was introverted, but realistically I was doing it because I had social anxiety. Looking back, hanging mostly 1:1 made me feel like my friends were more distant because there were so many people I didn't see for months that I always felt like I didn't really know my friends.
