I am the person that loves long and complex games. If I have an upper limit for those qualities I have not found it yet, because it must be higher than those of all the players I've met.
So, I can't really answer your question, but I think I can tell you why the rest of the table was pissed off, and maybe that will help you in some way.
You like a certain type of game, but it's somewhat outside the mainstream, so it's difficult to find a full group for it and gather them all at the table at the same time. You get excited, you finally get to play the game you have been itching for. You're really having fun. Your strategy starts paying off. And then you don't get to see it to completion because one person gets up and leaves. It might be weeks or months before you get another chance. You got your hopes up and then got left hanging. That sucks.
A similar situation is if you talked somebody into a game who didn't want to play at first and just end up doing you a favor. In my experience, 9 times out of 10 they're not going to have a good time, and they'll drag the rest of the table down with them.
But here's the kicker: After some painful lessons I know those things now. So I don't nag people about playing with me anymore. I ask once, and then a no is a no. And I don't invite people who I know have a short attention span to play long games with me. And I sure as hell don't schedule a game night on a weekday where everybody needs to work tomorrow.
The person putting together the table has a responsibility to curate games that fit the audience or vice versa. Everybody else attending has a responsibility to be transparent about their availability and preferences.
