I've been married for 35 years and happily married, although I know what you mean. If anyone says their marriage is perfect they're lying! Yes, you are getting a raw deal if you aren't the jealous type. Believe it or not men go through a type of menopause called 'Andropause' and it sounds like he could well be in it and doesn't know what he wants out of life. You have two options:
Hera the goddess of marriage.
Hera is the Goddess of marriage so she would be jealous of her husband Zeus's affairs.
Even though this is not a sports question, the answer is jealous. She is the goddess of marriage, so when her husband cheated, she got very, very, very jealous.
Hera by her husband Zeus. He did that because Hera talked to several Olympians in an attempt to drug Zeus, for she was extremely jealous of her husband's mortal affairs
Miracle of the Jealous Husband was created in 1511.
