He's selfish? or I'm overbearing?

WARNING - This is lengthy but it gives all the backstory you need to understand the situation.



Here's a little background:
Married almost 9yrs, 2 kids.

We've both been at our current employers since we met, I in a corporate setting, him in a warehouse setting.
My job is mentally stressful (been known to be in tears often enough), his is physically stressful (caused back issues that he is receiving medical attention for).

We filed bankruptcy towards the beginning of our marriage and continued bad spending habits after, never rebuilding our credit, just digging back into debt and making bad decisions. So here we are years later finally ready to correct the financial situation.

I have been the main breadwinner for several years now, even picking up a direct sales job that I love and have been grandly successful with. He works 3 12hrs on the weekends and stays with our children the rest of the week. At least twice a month he calls out from work, even if there's no time to cover it and we have to lose pay.

I feel like I work really hard, all the time and miss out on time with my kids because I have to carry us through. I am guilty of bad spending habits too, but am ready to be out of this rut and really fix our finances this time.

Step out of this story a little...about 2 months ago, he decided he wanted to be a car salesman part time in addition to his current job to help out with the money. My main concerns were:
1. He wouldn't make enough to cover what childcare would cost, making this pointless.
2. It would kill him. He only works 3 days and is tired the rest of the week...and now he wants to add more?
Finally this all came to rest when he found out he would have to work Saturdays, conflicting with his current job, so this idea went away thank goodness.

Well, now that we are getting ready to file bankruptcy again, he tells me that once it's done he's quitting his job to sell cars and that's it. No discussion. This is going to cut his pay in HALF.

I feel like this is the worst time to plan a crazy scheme like this...when we need to rebuild. Not to mention we'll have to find other insurance, add childcare to the budget, etc.

I understand that he is unhappy in his job, I'm miserable at mine but that doesn't mean I can walk out! I feel like this is a huge mistake for our family and like he's being selfish. I love this man, but it's really upsetting that he so non-chalantly can put his wants ahead of our needs.

I'm not here to bash my husband, I'm just at a loss.
I'd just like some outside opinions on this...advice welcome...especially from men!
