My husband gambled away his whole check

I just got done having a panic attack. Earlier today I made a post about seeing messages between my husband and adult son where he's thanking our son for something and my son is just responding with thumbs up and my husband is saying don't tell mom. My husband got mad I went through his phone and wouldn't tell me what it was. Just flipped it on me. My son had said he's not going to Thanksgiving and I called him to ask what dad said and to please tell me. He said he doesn't want to deal with this drama and he's going through his own stuff. I said I just wanted to know what dad was lying to me about so he told me my husband started gambling again and gambled away his entire check. We live in poverty and are pay check to pay check. We can't be on housing anymore until we pay them for the damage done in our last apartment. So me, my husband, and 13 year old daughter live in shitty one bedroom apartments and have a slumlord who's a creep and won't fix anything and does drugs. My son said my husband reached out for a favor and he's 19 and in college so he told his dad that he can't help us. He told me his dad said he needed help with something else. As I said our landlord has s a creep slumlord and it's rumored that he will give people a month extension in exchange for a sexual favor. He wasn't going to ask our 25 year old daughter because that's his baby girl and she's married and I guess our landlord is bi or something. So he asked our 19 year old to do it and he said no but said my husband started guilting him for like a week about us getting evicted and our 12 year old being diabetic so he agreed and gave our landlord a BJ then after went into our bathroom and threw up washing his mouth out and cried while my husband thanked him on the other side of the door. My son said he doesn't care about what our family is going through anymore and to leave him out of this.

I yelled at my husband and he said he knows he fucked up but we have another month now to figure it out. Our electricity bill is due next week and we don't have the money for it. I pissed that he dragged our 19 year old into this because now he's distancing himself from the family. My husband defended himself saying he had a choice and he chose to help us. My husband has always had a gambling problem and he promised he quit but now majority of our money is fucking gone and I'm scared. Our money is gone. Our son isn't coming for Thanksgiving and probably not Christmas because he's upset he was guilted into that situation. And our landlord is a fucking creep. I am considering leaving him. My mom is going to try to help us with electricity as much as she can. She told me not to be too hard on my husband because he could have done it himself and just cheated on me. And that our son chose to do it so he can't be mad at anyone but himself. My husband's gambling has put us in shit situations before but this is so much and at this point I feel I can be struggling financially by myself instead of with him.

Edit: I do want to divorce because I can't with him. But I'm scared on how we are going to get on our feet. We can barely keep our head above water with two incomes. I don't know how we can manage with one. It feels like no matter how hard I try to keep us up we just get knocked back down all over again.

Edit 2: For the people being shitty to me why even comment. Why am I being blamed when I didn't even know this happened. Why are women always blamed for men's shitty behavior and choices? I didn't know any of this happened. My son is mad at all of us when this had nothing to do with me or the choice he made. I am pissed at my husband for guilting him but I also wouldn't consider this SA because it was a choice and my husband is bad enough on his own for that. No need to add labels.

Edit3: Make things right with my son? I DIDN'T DO ANYTHING!!! I didn't know! His dad flat out told him not to tell me! I never and would never asked him to do something like that so his anger is completely misplaced. My husband is the one who should have to make things right and be the only one getting the anger. All I've ever done was work my ass off and take care of my kids. I took what little money I had to buy him a bed set for his college dorm. I don't deserve this!
