The OP is right about child support. If you get laid-off & can't find a job at the same level & take a lower paying job they will make your child support at the level you were previously earning. This happened to a man I know that was making half what his wife was earning. This man worked 2 jobs & had all his $ taken from both checks & had to move in with his Mom. She paid his bills. This went on for 2 years until finally he found a job at his past level of pay. They went to court but the judges -male or female did not care about the man. They even told him to go to another state to earn more $ . He had visitation and did not want to not see his kids but was told by the court the only important thing was that he should pay. I would convince her to move for graduate school & afterwards find a job you like no matter what the pay. If you divorce later you will have demonstrated a lower threshold of earning/living which may be respected by the court. I would stay married long enough to set a pattern of less $.
Yep that's exactky the situation I'd like to avoid. That's why, to the extent possible, it makes sense to scale down as much as possible while still married. As of now the grad school idea is probably my best shot
Okay, the thread is getting into the logically manipulative.....as others said, there is no gun to your head.
If you really want to make this happen, do the following: your spouse can not say no.
1) Register for community college classes (2)
today (the term starts this week. -- make them classes that you need to attend in the daytime, that are designed to help you get better marks, or be a better GRE, or freshen up your skills for applying to grad school.
2) Take a "sabbatical" -- move to part time work, or no work for the next semester, so you can focus on these classes. Do this tomorrow - after your classes are registered, and without telling your wife. give a written letter to your employer for thier notice, effective in 2 weeks.
3) Tell your wife. Be very very excited about a specific grad school,.. how all your dreams will come true, and all the money you will make if only you were partner, but you need this specific grad school to do it, (total BS in other words. as you will use this as a transition year while you think about it). how you are stagnating at work right now without promotions because of no grad school, etc.
4) In December, Extend the sabbatical to cover you for next term, while taking another 1-2 courses of interest, and either register for grad school for starting next year, or just keep extending.
5) If you take something interesting, but don't get a great mark, well that is ok, you can always retake it... or ...book a couple of classes in EUROPE that the two of you move for a term to live over there temporarily...
Others have pointed out that a change of living condition will do wonders to your wife's perspective. It may not be in the direction you planned, but certainly a temporary move away from the NYC trap you are in for at least 3 months will be a huge value.
She may or may not buy it.
The above is definitely possible path to take, and my spouse essentially did this to me, minus the europe, trapping me into sole income earner status without FU money for many years..... but we are still married and talking, and even like each other.
....
By all means, get counselling, as you will be doing most of the above without talking to her about it, so you need a place to discuss life goals.
