YTA your bf needs some space and you should be more considerate of his hobbies. Maybe he needs this to be thriving in his life and tbh you should ask yourself if you're not already abusing him. If I were him that would be a massive red flag to me. Have you thought about cutting all relationships to appease him, that would be the least you can do
the joke is that you have your priorities set straight.
No time for relationships when you could be learning about the kernel my friend.
also to be clear, it's not loneliness if you're content with being alone. Alone, and lonely, are two separate sides of the same coin. You can feel lonely in a room full of people, and you can be/feel alone when around nobody, without feeling lonely.
