My son got approached to join a gaming team

I've always had I guess a bias to gaming because I had an ex literally choose to play video games over me so I always said I would never be with another gamer. Then my son ended up being a gamer. He does esports and he plans to just be a streamer when he grows up. I was honestly very against his hobby at first and still don't know how I feel. He asked me to come to one of his esports competitions and I did and I would be lying if I said I didn't get a little sucked in. My son and his friends were on their own team together and when they won I did jump up and scream. It felt just like watching one of my kids win a game or do well on a dance recital. My son got approached to join an official gaming TEAM in our city. They go to a lot of competitions. I have had my worries and my boyfriend has said my son will just find a gamer girl who loves to game as much as he does and that's if he even wants a relationship. He's never shown interest in dating and he's almost 17. He just likes to game, hang out with friends and family and do his own thing. I am realizing that I think a lot of my issues were a me problem and just because I've been neglected for video games doesn't mean my son will do that to someone. Maybe he will find a gamer girl (or boy) that he falls in love with. But I realized I shouldn't have let my personal issues cause me to not be supportive of his hobby and I regret not going to as many competitions.
