When your mother-in-law can't take care of herself, will you put aside past contradictions to take care of her?

I won't take care of my mother-in-law, I will keep myself busy and do other things. I will tell outsiders that I am really too busy to help, just like my child is young. Let my mother-in-law help her say that she is too busy and unreasonable. I am anxious when my mother-in-law is ill, but I have no time and no way. If my mother-in-law makes irresponsible remarks, I will tell her that I have no obligation, just like the way she talks to me. Not only did I not take care of her, I didn't even give her money. I will tell others that I can't help it without money. She wants money herself, and I will say that you don't have a capable son, just like when she married her daughter-in-law for nothing and took my husband's money before marriage. When I was angry and complaining, she told me who told you not to look for a rich husband's family. My mother-in-law is ill, and I also deduct money from others to visit her through me. When she asks, I'll tell her it's for my face, not her. Just like when I gave birth to a child, my husband's relatives gave me money through my mother-in-law. I hold a grudge. My mother-in-law gave it to me, and I will return it all.
