Would you continue to live with someone you weren't happy with if you didnt have anywhere else to go?

It's a big world. There is always someplace to go.

I would probably decide to stay where I was [i]for now.[/i] And I'd make it a point to spend as much time as possible finding that place and making a good viable plan to get there ASAP.

I left and ended up in a bedsit for a while. It was depressing but eventually things changed in a manner that wouldn't have if I had stayed

It's possible, depends on how mature and pragmatic the couple are. Ex-couple! Lol
