I’m the same way but I’ve noticed it depends on the friends. I think it would help to respond to texts but if you don’t feel like hanging out that’s ok. I’ve noticed that the friends I don’t see as much usually want to do expensive things but my very best friends love to just hang out, go for a hike, just talk, and then yes at times we dress up and go out. If you want to keep these friends, maybe just make some time here and there to meet for coffee. But if they can’t accept that you’re not always free or want to go out, that’s kind of immature in my opinion.
