Was his life nothing? Had he nothing to show, no work? He did not count his work, anyone could have done it. What had he known, but the long, marital embrace with his wife. Curious, that this was what his life amounted to! At any rate, it was something, it was eternal. He would say so to anybody, and be proud of it. He lay with his wife in his arms, and she was still his fulfillment, just the same as ever. And that was the be-all and the end-all. Yes, and he was proud of it.
I wanted to run after him, but remembered that it is ridiculous to run after one's wife's lover in one's socks; and I did not wish to be ridiculous but terrible.
I think you need to have people around you who can remind you that, actually, what you just said makes no sense. Fortunately, I have my wife to do that continually.
God bids you not to commit lechery, that is, not to have sex with any woman except your wife. You ask of her that she should not have sex with anyone except you -- yet you are not willing to observe the same restraint in return.
