Would you go just to be supportive?

I hate video games and I hate gamers. I have dated too many gamers and it ended with me being ignored for video games. I have made sure all my kids have done different sports. Scouts. Clubs. My 17 year old has tried them all and he still drifted to video games. He saved up to buy his own game systems and video games. Because we live in a world where you can make money for stupid shit, he wants to be a streamer/professional gamer. So he has gotten into esports and has been to a few esports competitions. I've never been to any. I don't like it. He has one coming up and he did personally say "You don't have to go. I know you hate video games. But I would like you to." Now I feel really bad. I don't like that I knocked something he really liked. I just don't want him to treat girls how I was treated where I was basically ignored for video games. My fiancè made a point in saying that he will probably just find another gamer girl for him. I feel bad. I don't consider video games a "sport" but I know he wants me to go.
