I also thought that was rather touching ,when he referred to his situation back then as some very wet day
Just before that he declares
it was a very great object with me at that time to be at sea, - a very great object . and She did all that I wanted. I knew she would. - I knew that we should either go to the bottom together, or that she would be the making of me
I also wonder if he meant for Anne to know how he looked upon that time? If it is his bitterness showing. He must understand that she'd been listening and reading more into this than the others could possibly do.
