How long do you think a woman should financially support a man before she call it quits?

@SW-User I think it depends on the terms of their agreement. If the man has a reason for not contributing financially but does other things to provide ( keeps the budget, owns the car, cares for the kids so the woman can bring the income) the relationship should be above the finances.
Either partner leeching off the other one is a red flag. I would move along.
