It is your business what you choose to tell your W. I agree, if you can meet your financial obligations and meet your co-parenting duties it is not her business unless you choose to tell her.
The issue I have with what you posted is you are FEARFUL to tell her you don't have a job because "no woman wants to be with a guy that does not have a job".
By not telling her you don't have a job out of FEAR of what she will think (or not think) you are attempting to control how she reacts.
If you don't want to tell her than don't. Just be sure you are not telling her for the right reasons. If it is none of her business then great. If it is out of fear over what she will think, well, not so good.
