Introvert who never wanted to socialize now organizing game nights and craving connection

I feel a much stronger pull to be with people than I used to. It used to be that if I had my close family, a good relationship, and my online friends, I had enough. My current relationship is the most energizing and fulfilling I've ever been in, and yet I also find myself wanting to organize game nights with friends, or go to parties with lots of people. I want to meet people and grow my connections which I never cared about before. The idea of socializing seems fun and desirable to me where before I would dread going to parties even when it was people I liked. I'm more comfortable in crowds, in cities.
