This is really unhealthy spending. You need to delete your information from all of your online accounts and hand all of your cards over to your husband. This may be too blunt, but you're an adult who is aware that what you're doing is partially the result of a manic or mixed episode. I know it's difficult, but the responsible thing is to make sure you don't have access to any resources that will allow you to make these purchases while you're in an episode. You're perfectly capable of doing that, even while you're manic.
