I Have An Experience Yet To Be Experienced

About to meet with a new friend to play guitar together. I'm so nervous because I had such bad experiences with people that I'd much rather have brief interactions than to actually try and be friends with people. But he's expressed several times that he'd like me to play in his jam group. They also speak Deutsche. I speak svenska and some Deutsche. He also knows I'm trans and the other members know too. And they've been asking for a little over a month now.
I really would love to be in a band or a least have some playing buddies because besides my girlfriend, I really don't interact with other people very often. So I've been making sure to not get my expectations up too high. I'll go have a jam session with them and hopefully they'll want to play again some times if not at least I have it a shot.
