Unbelievable, author, a 1-in-1 situation like mine. If you read, tell me how it ended.

I'm 30, girl 25, on the verge of collapse, now offended, moved out to live with my mother.
We met and began to live with her mother, where she lived. Naturally for me it was a temporary option, because for a long time he lived far from his parents and was used to solving everything for himself. And her mother sat at home at a laptop, on purchased sick leave, and her daughter was busy around the house, cooking, cleaning, taking to the hospital, and so on. At first I wanted to help, it was a pity, it was work, and they also force me to do it at home. Then her mother decided when, where, why she had to go, there was practically no life of her own. While I was working they went shopping or somewhere else and always everywhere her mother was the initiator. I'm tired, scandals have begun, my mother-in-law is offended, expresses to her daughter, my daughter tells me that she is just helping her and nothing special. I forgot to say that the girl had a son, she was 2 years old at that time. Somehow he persuaded to rent an apartment and move. Very convenient, our work, garden 5 min. on foot. We didn't get married, although we wanted to. She goes to her mother every other day at least, they call up every day, then take her to the hospital, then cook, clean up, pay for housing and communal services, in general, everything. Everything is complicated by the fact that she, mom, is very sick, and it is really hard for her to do all this now. I am not against help, but the constant feeling of her mother's presence is exhausting. If we have a scandal, and she refuses her, then she will scandal. I stopped communicating with my mother-in-law. And the girl communicates and drives as if nothing had happened. I swear, communicate and drive while I am away. Once they had a fight, he said that he was against her going to one place, at the behest of her mother, she went anyway. And so we lived for 2 years, with a double life, it seems that we had our own plans, on the other hand, you know that there is still a mother who is not going to let her go anywhere.
The girl honestly tried to refuse her somehow, but she made tantrums, a bad daughter, blackmail, threats. Then she stopped, and we fought, often. I also hate her mother, as she tried to put up, she says that she will buy her a car, despite the fact that we have, so that she has her own, I kind of don't give a car sometimes. And the girl is tired of everything, but she doesn't want to leave her mother, and I'm not ready to be the third. The husband is the head of the family and the head of the wife, not the mother, I think so. In short, a vicious circle. And now I think either to leave her with her mother, or to endure, to wait for her to move away from her, but this can be waited all my life, this is upbringing.
I love her very much, so I endure, I came to my mother-in-law, she says I am to blame, I left money for them to live on. The girl does not communicate with me, wants to leave, I try to return her, I write sms hating, I apologize. But I myself think whether it is worth it, or whether it will be resigned. I love the girl, although it seems she doesn't really appreciate it. I, too, tortured her with scandals, but I was tired of enduring a close union with my mother. My parents help us, they give the child and her gifts, it's not enough for me, I don’t mind, her mother didn’t help, but we always owe her, and the girl doesn’t even oppose it. Also, her mother was not her mother, but adopted.
Maybe I'm wrong in something, advise, is there a way out, or just go?
