He was brilliant in physics, not physical relationships. He married his fourth wife because he had a dream with a pool table where he couldn't score a ball for goodness' sake.

It doesn't make the story any less interesting, but she was just a girl he dated. He didn't marry her. Also he married three times, not four.

He just had difficulty finding a woman who met the standard set by Arline Feynman.

I wonder how many husbands and wives wrote letters like this in August of 1945.

"For small creatures such as we, the vastness is bearable only through love"

Important context is that this was his first wife, his childhood sweetheart who was already terminally ill with tuberculosis when they married. He was also working on the Manhattan Project at the time; while there were, no doubt, warm bodies around, some of them radioactive, this wasn’t either of his later two marriages.

Hi, do you have a reference for this? I think you may have misunderstood the timeline.
