<human>: Give me a shortened version of the text

This may be the dumbest post /r/relationships has ever seen, but here goes...

My boyfriend of 3.5 years really loves American football. He follows the football subreddits, watches all of the games, has a fantasy team, talks about it with friends, goes to games... I mean, he doesn't paint his belly in his favorite colors and flash TV cameras, but he does like football quite a bit.

I, on the other hand, hate football. I think it's stupid and I find the NFL to be one of the worst organizations ever. I've tried to get into football in the past with exes, but I can't do it. I just hate it.

So I want to be supportive of my boyfriend. Football is an interest of his and it makes him happy. But whenever he brings it up, I have to fight the urge to sigh and roll my eyes because that's how much of a jerk I am. I want him to be able to openly talk about the things he likes and not feel like he's inconveniencing me or being judged.

Today we were debating something silly (not fighting) and I said that I found grown men who argue football online completely silly, not realizing that he does it. It really hurt his feelings and I felt awful. I apologized, but it made me realize that I want to support his interests rather than push my own agenda.

I'm probably overthinking this, but whatever. He means a lot to me.
<bot>: I hate football, boyfriend likes football. How can I support his interests without seeming disingenuous or coming off as rude?
