I hate people like this because they’re just miserable on purpose.

My partner doesn’t like Marmite and I do. Solution, I buy Marmite and she doesn’t eat it.

Just buy the peanut butter you like, as well.

It is just peanut butter, not like he gave up on his hobbies. Unless ofcourse peanut butter is the one thing he is living for. To me it sounds like he can’t be bothered to deal with two jars of peanut all the time so he just said “eh fuck it”
