If my partner and I don't agree on something, he doesn't just do it regardless of what I think.  And if he did, he wouldn't be my partner.

I think I've asked this before, but what are you getting out of this relationship?

Making a financial decision can be a very broad spectrum. Does this have to do with paying bills or setting a budget or is this something that he/you want to splurge on that is a "want" not a "need"? Is this a major purchase like a home or car, or is this something minor in the long run but a pain in the butt right now?

If my partner felt strongly that this choice was going to better our family and I disagreed I feel like that is when you get a 3rd party financial advisor involved. You can talk to your local credit union, or accountant or other financial professionals for advice. I don't have all the answers and neither does my partner, but we respect eachother enough to get all the facts if something in major and come to an agreement together. 

Some good advice I once got was that if one person wants to do something, and the other person does not, the «No» must win. That way, both parties are comfortable with the way things are going.

Tank, I think your DH is a tool, in general. He does what works best for HIM regardless of whether it bothers or hurts you.

Specifically to your question, though, it depends on the situation. If my spouse wanted me to recklessly spend money on "the family", I said no, and they said they were going to do it anyway, I would think my spouse didn't actually care about me and our family - only their wants. However, any proposal to spend money would be met by me with a "I'm uncomfortable as this is currently presented, so can we come to a compromise?" I'll rarely say no outright because, even with separate finances, DH and mine's financial health is tied to one another. It's unfair in our relationship for me to tell him how to spend his money (and vice versa) without first having a conversation about how, why, when, etc.

Without knowing more of what you're talking about, it's hard to say.  For instance, if my SO told me he wanted me to work more (or fewer) hours or sell some assets, or something like that, for the good of the family, and I didn't want to do it, I'm at a loss as to how he would "fix" that.  If he wanted me to contribute more money to joint finances, it's not something he could "fix" if I refused.  So I'm struggling to picture the situation you're describing, and whether what he's asking for is reasonable and whether it's something that truly would benefit the whole family (including you) or just him and his kids.  

Yes, it's difficult to tell, each situation can be different.

My ex-H was furious with me that I wouldn't mortgage the house in order for him to have the cash to start a small business.  Without a business plan, without talking with a bank, without doing anything except looking at storefronts from the street.  Oh, and I'd be the one running it.  He'd be out there finding product while I did everything else.  No.  I think that was a cause of our divorce among other things.

My DH wanted to buy a new cable package for sports.  I don't watch sports, couldn't care less.  I said no.  He said then I'll pay it myself.  That was acceptable.  He wants the hot tub fixed?  No, unless our other home repair debt is paid off first.  He's ok with that. 

Most of the time we can solve financial dilemmas by doing the math.  Should we refinance the house?  Crunch the numbers and you get an obvious answer.  Should we replace an aging car?  Well that one is trickier because you can only estimate future repair costs, but again, we crunch the numbers under various scenarios and then make a decision together.   If we can’t decide, the default option generally wins which is not buying a car.

He's making this a hill-to-die-for? Idiot. FFS

ETA: this isn't about the car, is it? DH is peeing on a fencepost for some other reason.  Since I have been known to let my inner bitch out from time to time ... I'd tell him to stuff it. Your car. Your funds.

Oh wow... Ok, this is a little crazy. That is your car and like others said you already made a commitment to make those payments. What does your divorce say? I am sure that you can't just dump a car on your ex. I would have never signed a decree like that! With your H stating he would "fix it for you" -- that sounds so threatening. I don't like this at all!! I don't have any advice, but I would certainly tell him to back the F off!

I would not give the car back to my ex.  First, that wouldn't be fair to your ex.  Second, if he just co-signed it, then you signed the loan as well, and if your ex doesn't make the payments, you'll be liable anyway (if I'm understanding the situation correctly).  Is your car upside down on its loan?  I'm having difficulty figuring out how giving a car away puts you into a better financial position.  Do you just have the money lying around to buy a new car?  Would this new car be an upgrade, a downgrade or a lateral move?

As for getting another job or working more hours . . . Do you have spare time?  What is your current financial situation vis-a-vis DH?  Does he make more?  Does he work more?  Who spends the most money?  I'm assuming since he has kids, it would be him.  So maybe HE should work more.  Who does the bulk of the housework and the childcare?  If you were working more, what would have to give?  Do you *want* to work more?  This is another question that can't be answered in a vacuum.

I'm curious as to how he's going to "fix" this for you.  I don't like the sound of that.

he wants me to give my car back to him so he gets stuck with the payments and he wants to buy a car outright so I don't have car payments.

If you can afford to buy a car outright (so you don't have car payments), why not just pay off the car that you have? Voila, no car payment. Why give the car to the ex? Which means everything you've already paid on it was for naught. Makes no sense.

How is your husband going to "fix" it? It's your car, he can't legally do a thing with it.

And if he wants you to work more, to have more money and save, save, save, how does giving a car away, wasting the money you've already paid on it, and buying another one outright, make ANY sense?

Is he feeling okay?

I really don't like your husband.  He is spineless little infraction of a man who can bully you but can't tell his demon spawn to keep the f*ck off the couch.  

I'd keep the car and dump him.  He's a user and abuser.
