"I look at him with the nostalgic affection men are said to f..." — Margaret Atwood quote meaning

I look at him with the nostalgic affection men are said to feel for their wars, their fellow veterans. I think, I once threw things at this man. I threw a glass ashtray, a fairly cheap one which didn't break. I threw a shoe (his) and a handbag (mine), not even snapping the handbag shut first, so that he was showered with a metal rain of keys and small change. The worst thing I threw was a small portable television set, standing on the bed and heaving it at him with the aid of the bouncy springs, although the instant I let fly I thought, Oh God, let him duck! I once thought I was capable of murdering him. Today I feel only a mild regret that we were not more civilized with each other at the time. Still, it was amazing, all those explosions, that recklessness, that Technicolor wreckage. Amazing and agonizing and almost lethal.
