He wrote more pitiably a year later:

Rue d’Anjou, Paris, October 24, 1807.

I can do no more, my dear Sally, than simply give you the latest news upon this the anniversary of my marriage, for I am still here, and so far from things getting better they become worse every day. We are more violent and more open, and more public, as may really be said, in our quarrels. If she does not mind publicity, for a certainty I shall not. As I write the uncouth word quarrels, I will give you an idea of one of them.

In the first place be it known that this estate is a joint concern. I have as good a right to it as Madame, she having paid rather more in the beginning, but I an immensity of money in repairs and alterations, &c. &c., besides a great deal of my own time and care spent while we have been here.

I am almost afraid to tell you the story, my good child, lest in future you should not be good; lest what I am about relating should set you a bad example, make you passionate, and so on. But I had been made very angry. A large party had been invited I neither liked nor approved of, and invited for the sole purpose of vexing me. Our house being in the centre of the garden, walled around, with iron gates, I put on my hat, walked down to the porter’s lodge and gave him orders, on his peril, not to let anyone in. Besides, I took away the keys. Madame went down, and when the company arrived she talked with them, she on one side, they on the other, of the high brick wall. After that she goes and pours boiling water on some of my beautiful flowers.

And the wretched climax came the next year:

Rue d’Anjou, St. Honoré, No. 39, Paris, April 12, 1808.

After what you know, my dear Sally, of my domestic troubles you will naturally be anxious to know the present state of things. There are no alterations for the better. On the contrary, much worse. I have suffered more than you can imagine for the last four weeks; but my rights are incontestable, and I am determined to maintain them. I have the misfortune to be married to one of the most imperious, tyrannical, unfeeling women that ever existed, and whose perseverance in pursuing an object is equal to her profound cunning and wickedness in framing it.

It is impossible to continue in this way, and we shall separate. I only wish it was well over. It is probable I shall take a house at Auteuil, a very pleasant place, with the Seine on one side and the Bois de Boulogne on the other, about a league from Paris. I have seen a very handsome house there which I can have—rather dear, but that matters little can I but find quiet. It would be truly unfortunate, after the King of Bavaria’s late bounties joined to former ones, if I could not live more independently than with this unfeeling, cunning, tyrannical woman.

Little do we know people at first sight! Do you preserve my letters? You will perceive that I have given very different accounts of this woman, for lady I cannot call her.

Now, my dear Sally, as soon as I get settled, enjoying again independence, I shall wish you to join me.

In the meantime believe me your affectionate Father.

The Count bought the lease of his villa at Auteuil in April 1808.

For the last two or three months of his most miserable married life he was seriously ill. The nature of his illness is seen by the remedies that benefited him. He told his daughter that the King of Bavaria, having knowledge of his domestic discomforts, had recently written him a letter that had done him much good. ‘He speaks most kindly to me, and encourages me to bear my misfortunes like a man of firmness who has nothing to reproach himself with.’

The separation took place amicably on June 30, 1809. He soon after wrote to his daughter:

I find myself relieved from an almost insupportable burden. I cannot repeat too much how happy I am, gaining every day in health, which, from vexations, had become seriously deranged. I am persuaded it is all for the best. After the scenes which I have recently passed through I realise, as never before, the sweets of quiet, liberty, and independence. My household consists of the most faithful, honest people, attached to me, without dissension, bribery, or malice. And, above all, that eternal contradiction. Oh! happy, thrice happy, am I to be my own man again!

Later he wrote:

Madame de Rumford is well. I see her sometimes, though very seldom. After what is past a reconciliation is impossible. She now repents of her conduct, but it is too late. The less I see her the better. I now enjoy peace and tranquillity, and my health improves every day.
