A wife had sex with her husband 3 times in 6 weeks and he's the jackass?
Yes, which is why she did not have sex with him.....Would you have sex with a computer? A spreadsheet?
Are you a woman? You don't seem to have a good grasp of logic. You're stating here that the wife didn't have sex with her husband because in the future he would compile a spreadsheet chronicling her refusals. That's logically incoherent.
Look, men have been arguing with women since time began. Men recognize that women have memories like elephants and can recall, when it suits them, the tiniest and most inconsequential details of interactions they've been involved in from years, even decades, in the past and zing the husband during an argument.
For this husband to feel he needed to document the outcomes of his sex appeals it's extremely likely that the wife didn't accept his claims that she was refusing him and his own memory couldn't list off the particulars that she demanded. So if the man can't rely on his memory to satisfy his wife's demand for proof, best document the refusals as they happen.
The fact that the man felt it necessary to document these events strongly suggests that the wife refused to believe him when he was offering his recollection of the events that transpired between them. That was the wife's first mistake. Anyone who is married should recognize that impressions count just as much as reality - a misunderstanding can be as hurtful as an intended action. If the husband was feeling that they weren't having sex frequently enough that right there is problem that needs to be addressed rather than dismissed. Clearly it was dismissed, leading him to feeling the need to actually document their history.
