People in long term relationships, but not married, will you answer some questions?

We’ve had some Q’s on Fluther about the “piece of paper” not being necessary or not changing anything. My questions are:

1. Would you feel comfortable not working, being supported by your SO, if your not married?

2. Moving and leaving your job because your SO was offered a big salary and career move?

Do you think those types of situation are different in marriage than when not married? What if the careers for both are not easy to get a job and are big money makers? Like high positions in corporations?

Anything you can think of where the piece of paper really would affect decisions you would make on a very practical level?

I know people move to be near bf’s and gf’s, but that is often when the people are young and new in careers. I don’t know how often that happens in very established careers without the promise of marriage?
