Geez, this running out of money and expecting your wife to dysregulate over it sucks. However it sounds like you are doing about as well as you can. Good luck.
It sounds like your job search is going well enough... .you just haven't quite got the winning ticket yet. (Note: On those jobs you were the #2 man for... .perhaps you can follow up in a couple months... .just in case the #1 applicant didn't work out. Sometimes things go south pretty quickly.
Consider some boundary enforcement changes when you resume work/income: Something like this:
Wife, you and I seem to have different ideas about how to handle money, and it causes too much conflict between us.
I've been letting you manage our joint household expenses your way. I'm going to keep doing that, with most of my paycheck going into our joint account.
I will be putting a smaller amount of money into an individual account so I can take care of my car expenses, my phone, my clothes, etc. in the way that works for me.
If you want to have an individual account for your personal expenses in addition to the joint family account, I will support that.
None of this is a discussion/negotiation. You may next negotiate the amount you take into your account with her.
It just seems that keeping yourself financially safe... .and getting out of the household money debate farther is a double-win for you, FF. I expect that your wife will object loudly at first... .and eventually be happy with the change.
