Albert Einstein wasn’t too happy with his wife in 1914, after 11 years of communal life. He thought it’d be good to stay with her for the sake of his children but he wrote some kind of list of conditions, that she had to accept for them to actually stay together.
Here is the list:
You will make sure:
that my clothes and laundry are kept in good order;
that I will receive my three meals regularly in my room;
that my bedroom and study are kept neat, and especially that my desk is left for my use only.
You will renounce all personal relations with me insofar as they are not completely necessary for social reasons. Specifically, You will forego:
my sitting at home with you;
my going out or travelling with you.
You will obey the following points in your relations with me:
you will not expect any intimacy from me, nor will you reproach me in any way;
you will stop talking to me if I request it;
you will leave my bedroom or study immediately without protest if I request it.
You will undertake not to belittle me in front of our children, either through words or behavior.
His rational thinking might have abandoned him when he wrote that or perhaps, that’s the way it worked.
