Yes because you are finally standing up for yourself and not letting her steamroll you so she's gone to Plan B which is "get mean and angry until he comes back under my control". If you stick to your gameplan then at some point you can expect Plan C which is "cry and pout and act miserable until he comes back under my control." Plan D is "dangle the carrot" where she will make you promises of rekindling the relationship, if only you will just leave the house for a few months. When that fails she will loop back around and repeat.
