Loss of money/ men/land

My husband use to work in the oil field and make pretty good money and we were pretty set. But now he left and we have bills running up because he not making what he was and things are very hard. We have been fighting and he gets very mad at me when I buy couple things to make me feel better when I just had a baby(and it’s just like a shirt since I don’t fit into my clothes anymore.) and he blames me for not having money and just takes it out on me. He has land in his name that we pay taxes on and I guess we can’t sell that until his grandma dies? Since it was a family thing but it’s in his name?? Not hers. I don’t know what to do and need advice how to cope what too do because i do what I’m suppose to do and yet it’s still my fault. And why he can’t sell his land?
