It's probably not something that can be overcome. Scorpios think they are a law unto themselves. They do operate according to their own rules. But they are also law-abiding and don't really want to hurt others, contrary to what people often think. Also, the Leo rising is another fixed sign like Scorpio, so you would have a devil of a time trying to change him. Leo rising means he's bossy and likes his own way. But Scorpios are loyal in love, so is Leo. So if he cares about you enough, he won't hurt you. Talk about it with him and let him know what really bothers you. If he cares enough, he will try to accommodate you. If he is hurting you, and won't change his ways, then you have to decide if he's worth the trouble. It sounds to me like you are just observing these features of his personality, and that you really care. So as long as you accept him, and he makes some effort to curb the behaviors that bother you, hopefully, you can go on to enjoy a nice relationship. Good luck!
