Des, why should we have to feel sorry and guilty for something we can't control?

Hormones are hormones, it's not like we can change how they work through mind control.
Sally, my ex-father-in-law got in the habit of marrying younger women and then dumping them as soon as they hit menopause, picking up an even younger woman. Guess he finally got too old to snag non-menopausal women or couldn't afford any more divorce settlements, or both.
Sounds like this guy could have similar issues. Since you only have a few months invested in him, maybe it wouldn't be a bad idea to find a guy who's a little more mature and understanding of how women's bodies work.
