Situation: In an overzealous moment, I signed up to be on a team in this summer ultimate frisbee league my city has. Now, I'm really afraid to go because I don't know anyone there, and I'm only a beginner whereas most of these people are pretty good, and it's gotten to the point where I don't want to participate. My ex, who was the one who got me to sign up, now says that I'm just trying to avoid stepping out of my comfort zone and meeting new people, but I feel like if it's just going to give me unnecessary angst and anxiety if I go, then there's no reason. Also, I play ultimate every weekend, which I feel is plenty for me.
So, what do y'all think? Should I go or not? And if I decide not to go, what should I say to my ex to make him understand, or at the very least, shut up?
