I'm new here as well and couldn't help but post in answer to you questions. You said you recently moved in with him. Whenever there are routine changes for someone with Bipolar there is a chance that could trigger and episode. Have you also thought that if he didn't have Bipolar that he may have been upset as well? And as a result of his illness the reaction was magnified? There is some great info on this site that may help you. I just read a blog from the Bipolar Beat that is part of this site. Check it out and see if there is anything else that might help.
