Hi. My husband is disabled and in a wheelchair due to Muscular Dystrophy.
I can relate to your entire post. The physical things he can not do are not nearly as hard to deal with as his being home all day and frankly with his adjustment. He too is a tightwad about money.
I resented being supervised about money over every decision.
I finally started getting some cash every month that is my money, no questions asked. This eliminated our arguements over money and I don't feel like a naughty child. Plus, our budget is intact.
I think your bookcases were justifiable as they keep your house in order and save many hours in the future. Regardless of depression, he needs to apologize and tell your girls he was upset, overreacted, and was wrong. Plus, he is out of line for reacting like this over $200. He needs to stop it.
He should NOT be burdening children with ANY adult problems. He needs to vent to an adult(not inlaws), preferably a professional. I am sure he is depressed and I have suffered from severe depression so I know how hopeless it feels. He needs to deal with it before he loses you and is alone, only to have weekend visitations. I don't have stats, but many disabled people end up alone after their attitude, behaviors, and actions push their loved ones away. Divorce is hard on everyone and the expenses double.
My husband is not physically able to do many things. He can't breathe if he bends forward, he can barely stand, and he falls over if he bends while standing and can not get up without a lift. He got a second degree, began his masters, and then found out he was having memory loss. He was going to be a CPA, but he is so forgettful and slow no one would hire him and keep him on. Plus, sometimes he spends hours on the toilet because his muscles don't work. He gets exhausted and out of breathe then has to rest after transferring from bed to the wheelchair. He gets in the hospital if he catches the flu or pnemonia. He went to interviews and even offered to work for free if only people would give him a chance at a job, any job.
We could afford him to stay at home, but he wanted a job for his self respect. His body and mind are not up to it. There is a way to work and keep his disability checks coming. You can look online for info.
My husband is able to clean counters, write the checks(takes 4 times longer than it used to), assemble some things, half make the bed(very frustrating for him), get the van serviced, and run some errands(pill up medicines, deposit checks, transport kids). He has tried to do more, but he wears himself out and I have to redo it anyway. I want him to have some energy to play with our child.
There is good advice on here in case your husband is not thinking clearly, especially about making sure the bills are paid. Also, depositing your check into an account then transferring money for household bills sounds smart, but I think my husband would flip out and assume I was divorcing him. If your husband is not paying the bills, I would get a checking account and pay the bills myself. He won't like it, but you must protect yourself.
If you do seperate or divorce, you MUST hire your own lawyer to look out for your interests. Yes, they charge, but they will save you much money and heartache in the future. I hope you find support in real life. I know it is hard.
"Whoever makes the money controls the money" is ok with several ladies on here. It might be ok if I am making more money;-) , but I prefer "What is yours is ours; What is mine is mine." LOL
