So is being in a relationship just spending hours doing things you don’t want to do?

i grew up an only child so maybe I’m just not used to having to share my time doing things I don’t want to do . but lately I’ve been frustrated spending hours watching boring TV shows with my girlfriend and going out to clubs with her friends when I could be writing music or hiking or playing video games … is this just the sacrifice of having a girlfriend ? we’ve been together 4 years but I really started feeling this the last 2 years . i think about it often . Especially when work comes into the picture , I’d rather be spending money on what I want and my goals instead of food and gas to drive to go out to pick up her friends or for overpriced drinks at bars .
