Waiting to file til he has a job - way to play the system for more money! Good work. But it's a statistical anomaly when women pay men support. Not likely something to be concerned about, especially since it sounds like you don't work. Much more likely is his income will be imputed regardless of his current employment status and the judge will make him pay you.
There is nothing at all selfish about expecting adults to be self-respecting grown-ups and support themselves financially.
If he is able-bodied and capable of working, he's also subject to having an income imputed to him...which is pretty common.
You're smart to wait to file and you should absolutely protect the assets that you've earned from an undignified leech.
And I agree, divorce can be a wonderful new beginning...getting divorced was the best thing I ever did. Life just keeps getting better and better and I wish the same thing for you.
