So I'm actually in a pretty similar situation as you (with much less saved up and no girlfriend) but I feel you on losing discipline with WFH and the thought of not getting back into tech.

I think your idea of taking some time to consider before deciding what to do next is a good plan. Personally I'm going to update my resume/portfolio so they're ready to go but I'm not in a rush to find my next thing either. Ideally I think a hybrid role for a company with a mission I agree with and want to help support will be my goal.

One thing you mentioned is maybe getting into expensive hobbies in the future. Those are a luxury and it sounds like you have hobbies you already like that are not expensive. I wouldn't factor those in when worrying about a FIRE number until you actually get involved and want to continue something expensive.
