It doesn’t sound like this is a relationship that makes you happy, and you’ve just entered into an adult world of options and exploration. Personally, I wouldn’t waste time. How likely do you see this being long term and happy?
Additionally, while 18-24 isn’t necessarily a “problematic” age gap, you are in different parts of your life entirely. The amount your personality, interests, goals, social network, etc change between 18 and 24 is huge. If I had a friend that was dating an 18 year old at 24, I’d be very confused and a little concerned. When I was 18, I was still figuring out who I was, worrying about paying for college, trying and failing at relationships until I had made the mistakes and learned the lessons I needed to. When I turned 24, I was engaged, friends of mine were all graduated, some with kids, some married, and we were all well into a developing adult life. You should really take advantage of the time you have. I wouldn’t waste it on someone that isn’t willing to do the legwork to take care of themselves, much less you. You aren’t responsible for their depression, much less so at the cost of important years of your young adulthood.
Edit: I just saw your update, I’m glad you’re taking care of yourself
SW is for children is not a great take. It’s just not sci-fi, and shouldn’t be judged as such. It’s a space fantasy, and it leans into the camp and the suspension of disbelief. They use wings and aerodynamics in space. Destroyed ships “sink.” The good guys never get hit and the bad guys die in one shot. Now, the new movies were absolutely disappointing, but Star Wars was never sci-fi, at least not in the ways this discussion is defining the genre.
