My husband of 32 years has a Cancer Moon. His Moon is tightly conjunct Uranus in Cancer in the 3rd. And it is the trigger of a very tight t-square with Sun/Mercury in Aries in the 12th and Saturn/Neptune in Libra in the 6th.
He can be very emotional. But I have a Capricorn Moon. And I think we balance each other out. When our kids wanted something, like a new toy or permission to go out, they asked Dad.
When they needed help doing something like school work etc, they asked me.
We were good cop, bad cop. But they love us both because we both were necessary for their upbringing.
If one of the kids had a crisis, like a break up or bad grade, Moon in Cancer Dad got emotional and commiserated with them. He would agree with them that the teacher was stupid and wrong etc. lol
I would take the opposite stance and require them to show me the D paper and point out where the teacher was correct.
So the Moon in Cancer has importance for sure because it was necessary to balance out My Cappiness.
My husband is a very emotional, compassionate soul. He always befriends the under dogs. At his office, he knows everyone by first name. From the security guard and maintenance man to the CEO and the 'suits' as he calls them. He takes the time to get to know them all personally and he does so sincerely. I don't know how he does it.
For fun and relaxation, sometimes he peruses Kickstarter and GoFundME and donates small amounts to various people who need help. It feeds his soul.
I think it is good for you that you have the constraints put on your Cancer Moon by the Capricorn/Libra influences. Cancer Moons need to be reigned in a bit. It is emotionally overwhelming to be too consumed by too many emotional connections/situations.
My husbands Moon is in the 3rd conjunct Uranus. He writes animated cartoons and writes books and does lectures and book tours. Very uranian 3rd house energy to help feed his Moon.
