It's not only that they are not men for the whole life, but they could also destroy you.
Cancers can be placed into two groups - those who love their home, but are annoying, splitting hairs and critical, and those who are passive, lazy and uninterested. They usually get married because of benefits, inheritance or position, that is, for any reason that will make them easily come to certain goods or a good position. Even though he loves his wife and children, he will never be entirely satisfied with anything and will always find something that will provoke criticism or regret in him. However, as a rule, they are faithful - of course, only if all their needs are satisfied at home.
The only way to create marriage harmony with this sign is to follow him in all his endeavors blindly. Scorpios can't stand dominant women, they are old-fashioned and like to show who is the man in the house. However, they adore their wife and children and are successful at work, which enables them to provide for their family successfully. Deep down Scorpio's feelings for them are really noble, even though he will never learn to express them. If you can meet all of his immense desire, in bed and out of it, you could have a successful marriage.
This type of man requires wise and tactful wife, more than others, because he will notice her faults, imperfections and flaws. His interest in the world is huge - he wants to help and participate in everything, which sometimes makes it difficult for him to stay devoted to marriage and home.
It is not hard to live with this man, but due to his lack of feelings, great impatience for anything limited or strictly defined by rules, his wife will be forced to expand her horizons in order to be equal with him.
