She had a headache — and then some.

A fed-up, sexually frustrated husband documented every time his wife refused to have sex with him for a month with reasons like, “I’m too drunk and ate too much” and, “I might be getting sick” — and then sent the spreadsheet to her before she left on a 10-day business trip.

In retaliation, the wife posted the sheet on Reddit. And it went viral.

The document, which has since been deleted, also included snide side notes next to such excuses as, “’I’m trying to watch the movie’ (fell asleep 15 min later)” and “’I just came back from the gym, I feel gross’ (didn’t shower until next morning).”

The couple had sex three times in seven weeks — despite 27 attempts by the husband, his list showed.

On Reddit, the unidentified woman blamed their “crazy busy lives,” work stress and a recent weight gain. She said they’re both 26, been married for two years and together for five. She said she was hurt by the “sarcastic diatribe basically saying he won’t miss me for the 10 days I’m gone.”

While public responses were mixed, many questioned the marriage.

“Clearly the communication style in your relationship is s–t,” wrote one poster. “Fix it or don’t, it’s your marriage.”
