The Scorpio male is also known to be suspicious and can even be jealous. One thing you shouldn't do is to make him doubtful in any kind of way. He is the type who will give a margin of freedom to the person he is with in the name of love and he will trust the one he loves with all his heart. Breaking this trust can break him and push him to show the negative side of the Scorpio lover. The best thing that can happen is that he will just return to his brooding self. The worst is that you can bring the self destructive and pessimistic side he always had.
