<human>: We've (21f and 20m) been together for over 1.5 years. Things are pretty over the moon. He's incredibly patient and understanding. He humors me when I go rambling off on crazy topics. We support each other and care about what the other one is doing. We're different, but we work.

 We got into a discussion about the online game League of Legends. He's been big into it for a few years and loves playing it and watching the championships etc. Last night he mentioned wanting to teach me the rules so we can enjoy watching the game together...ok. I'm alright with this in theory.

 The problem is this game has an incredibly steep learning curve. His estimate was that if I actively tried to learn for a couple hours a day, I could probably understand the basics in two weeks. It's a game that I quite frankly have no interest in, and I told him so. I don't have a problem celebrating his hobbies with him. But I feel like this is akin to school work. 

 We're both in engineering college. This semester is particularly heavy for me plus I work part time. The idea of committing an hour a day (length of one match) to a game I'm not interested in is pretty unappealing.

 After we talked and I explained this, he understood it was a pretty big thing to ask and understood why I wasn't interested.

 My question to reddit is am I being selfish? My sole reason for taking an interest in the game is because he loves it so much. Personally it's just not something I want to learn. But I know relationships are about give and take. I don't want to take too often. We aren't fighting about it or anything. I'm more just curious what you guys think.

Can you condense the text into a few key points?
<bot>: boyfriend wants me to share in his hobby. I'm unwilling to because of the huge time commitment associated with just learning the basics.
