My wife and I worked at home together 1 room away from each other and I don’t mind it at all. We’re essentially together 24/7 aside from very minor errands. I wouldn’t have it any other way.
Different strokes for different folks though, some people need space and alone time, and that’s also fine. You find what works for you and your partner.
This relationship didn’t work out for her, I’d spend this time working on yourself and becoming a better version of yourself so that you have more options and more people interested in you. Get in shape, get yourself correct and suitors will appear.
