I want some honest feedback

So a friend of mine and myself have read a lot of the same series and have basically a 2 person book club. He got me to read the Cosmere and Dresden Files, both of which I love. He then suggested Wheel of Time. I really didn't care for it from the get-go. Right from book 1 I just did not like it whatsoever. But he's one of my best friends, he really likes the series, it means a lot to him, so I wanted to give it a fair shot. I didnt like book 1, I didnt like book 2, I didnt like book 3. But I listened all the way through the end of book 4. That's well over 100 hours of audiobooks. Nobody can say I didn't give it a fair shot.

So...I then discovered DCC and fell in love. So I immediately recommended it to him. He listened to HALF of book 1 and says "I don't like it, I'm not going to listen to it anymore".

Now, let's ignore the fact that he's objectively wrong to dislike DCC lol. Isn't that at least a little disrespectful? I put over 100 hours in to the series he recommended even though I didn't like it at all, just to give it a fair shot. He puts 4 hours into the one I recommend him, doesn't like it and just quits on it.

I'm a little salty, let's play the classic AITA game.
