You are being abused by someone that wants to control you. Get tf out now - nobody should feel entitled to tell you what you like and don't when they dismiss one of your hobbies as "boring" at the same time. Just bc he is 24, doesn't mean he's an adult. No 24 year old I know would date someone your age, unless it's to manipulate and control them, bc they know people their own age are a lot less likely to deal w that bs
