Am I in the wrong for being upset?

Some background to this first:

We get $444 in food stamps (please don’t bash this isn’t what this post is about). It is under my name, my husband and our son. We live with his parents and his brother (who constantly have people over). We do meals separately so this is why we are able to receive them. Yet my husband and I are the ones supplying food to the whole house, month after month. No one knows how to save or to help make it all last so the last two weeks we are going hungry (let me add I always make sure my son is fed, he is always fed) while I’m stuck begging my family for food money (and they are fantastic enough to help). This has continued to happen and even though everyone else eats the food, no one contributes but us. I brought it up to my husband awhile ago and he just got angry at me and basically started talking shit about how I don’t want to help after all the help I’ve received and that the world revolves around me. I told him that wasn’t the case at all, i didn’t mind helping because I KNOW I wouldn’t be where I’m at today without help, but I’m worried about our son and I feel like a piece of shit because I can barely keep food on the table. He went and told his mom that I was refusing to help anymore when I never said that. (Side note- that also isn’t the first time he’s gone and told his parents I said something completely opposite of what I’ve said or made up something to make me look like the bad guy.) When I was talking to his mom about how I believed it was unfair she told me:

“Well I did it when we first moved in so you can’t say anything about it being unfair.”

And kinda just brushed it off with a scoff.

So, now to why I’m upset today.

I go to check how much we have left, it was $92 and some odd change that my husband and I AGREED would be saved and spent on our son to make sure he would have food at the end of the month. But when I check it this morning, there’s only 28 fucking dollars left.

So I storm downstairs and wake him up and ask what he spent almost 60 dollars on. He gets mad at me and tells me he spent it on stuff for his mom and dad (which I normally don’t have an issue with but we had an agreement). I tell him that money was supposed to be saved for our son for the end of the month and he just gets mad at me and says things like:

“Oh I forgot I’m a piece of shit father, I don’t care or think about my son. You’re right.”

And just keeps saying things like this over and over.

At this point I’m basically in tears (being 31 weeks pregnant has made me super emotional). I keep telling him that this was supposed to be for our son and that now how am I gonna make sure he’s fed.

He tells me to remember that the food stamps are not just in my name. I fully understand this, but this could hurt our SON. He just gets mad, starts talking shit, rolls over and goes back to bed.

This isn’t the first time something like this has happened either. He’s spent our money without consulting me first and then gets mad at me when I’m upset about it.

Example:

1.) When we got our taxes back I specifically put aside some money to get a dresser. We still don’t have a dresser.

2.) My mom sent me some early birthday money and he went out and got what HE wanted. I got myself lunch and then still took his mom out for a nice birthday dinner.

She also works at a very high paying job (and I understand that it doesn’t account to much as bills are expensive and things) so I don’t understand why we’re the only ones contributing to the grocery bill.

I love him and his family with all my heart, I really honestly don’t know where I’d be without them as they’ve helped us so much... but I’m on the verge of leaving back to my grandmothers house until I can afford my own. I can’t keep going through this emotional stress and putting my son through this.

My only problem with leaving is I know that I’ll get talked shit on. He’ll tell me that it’s my fault he can’t come see his son because he doesn’t have a car and no way to make it 300 miles to my Nana’s. He said that I’ll keep his son from him which is not the case at ALL. When I told him I wanted to move out with him to our own place he got upset and when he was talking to our son (who can’t understand anything just yet) he kept telling him that he’ll miss him because he’ll never see him again. He’s said that I’ll have him calling another man ‘dad’. The list goes on... I can’t keep doing this. And I don’t know what to do anymore.

I know the obvious choice is simple- leave. But it’s just not that easy. It really isn’t and it’s not because I love him. I can leave and still love him, I WILL leave for the betterment of my sons life. But I’m just at am impasse. I WANT to make this work, but I can’t do that if my choices aren’t respected as well. I just need to know how to get that across to him, because he doesn’t seem to understand that at all...

I also wanted to add that he will come and complain to me about some of the things that happen in the house or how he’s tired of the disrespect he experiences but he refuses to do anything about it. We have another place to go to but he doesn’t want to leave his parents.

Update:

I hid the card to make sure I had the last of it for our son. When he asked me where it was, I told him I put it up to make sure I would have money for our son. He got mad at me and kept bugging me for it and then stormed off and said-

“It’s not just your fucking food stamps.”

I’m beyond irritated and I’m about to leave. I’m at my ropes end and I just can’t do this anymore.
