He will them comment, I thought me being in a nursing home would be less then a burden for you but it hasn't worked out that way! No it hasn't because of the way he has been.
I do think it's because of your response to him, though.
You must start putting yourself first, and just refuse to do all these things.
Think about the Wiltshire Farm Foods one - he tried them before and didn't like them. Now, just to cause you bother, he wants you to get them again.
It's all manipulation. Please, for your own sake, just do what is reasonable. Stop answering all his texts. Don't pander to him. Stop doing his washing. It's just him controlling you @Totallybannanas
Step back. Stop. Look after yourself and pay him no heed. He isn't even grateful anyway.
It won't matter what you do, it won't be enough. He'll think of another way to make your life a misery. It'll never, ever be enough.
Start looking at his messages every two or three days. Don't look at them otherwise.
Stop doing his washing. Don't do any cooking. This is all about his need to exert control.
