If i said "I think it's time we separate everything to reflect our true separation" or something like that, then what will happen to my financial comfort? There. That's my fear.
This is why you should have a consultation with an attorney. Not to start a divorce, but to find out what the likely financial outcome for you would be IF you were to divorce.
Knowledge is power. You might discover that between child and spousal support you would be ok. Or you might find that you are best off this way for now and start planning how to increase your income in the future.
