NTA If you can, take your bro out alone just the two or three of you. Maybe w him and his friends? Ice skating is cool and cheap. Just pay for him. It’s his b day so do what he may like or want. I see mom’s perspective of wanting a whole family lifestyle but she also needs to understand like being younger, if the family doesn’t like them then it probably is not the best Fit. But also if she does see it long term you both also have to make a small common ground on it bc she’s happy
