Leos and Scorpios can be great together, but that is not always the case. If things aren't working out, you should try talking to someone, maybe a therapist. Try to figure things out. But if you two just don't get along now that you live together, maybe it's better for you to separate. I know it's hard, but it's harder living with a negative person who constantly brings you down. You can still love him and keep him in your life, but maybe as just a friend and see how things go. In the end though, don't you deserve someone who makes you happy? I think you do. Scorpios have a tendency to be very negative and it sounds like your partner is that. Leos are more positive and upbeat people who need someone likeminded around.
