Depends how much Scorpio is there. Those are just sun signs that you have in mind, so you might be nothing like Scorpio and he might be nothing like Cancer. Anyways, typical Scorpio and Cancer should get along, unless you are unemotional *****, because cancers are sensitive people.
Listen, what matters is aspects, that you two have together. His moon sign is sensitive as well, because it's in a water sign and yours in a fire sign, which is not sensitive at all. Those two moon signs wouldn't get along. What matters is what aspects you two have in common. In fact, Indian, Vedic astrology is more correct than that of Western so you should check it out.
Humanity spends 100,000 struggling toward reason and idiot clowns volunteer for a world of magic ba<x>sed on 6000 year-old Sumerian agronomy, astounding.
