I don't really like to speculate on your private business. Taurus Sun and Moon means you are a person of few words, and only say what's necessary, speak when there is something important to say. But Taurus is a sensual sign, and Cancer is romantic. You need to communicate and talk about the issue more. A Cancer Sun and Moon is shy and Cancer men do seem to get divorced frequently and have problems communicating in marriage, I don't know why. Their opposites in sign and sex, Capricorn women, don't have these issues. You are both gentle people, and I will take a guess are shy about discussing your needs and what you like. You are both romantic, try to reconnect, have some candlelight dinners, find some time for yourselves, and take it from there. Good luck.
