Never let an A move into your house if they are not in honest, authentic recovery because it's not a question if they will relapse it is only a matter of WHEN will they relapse!
Her only hope to get free is to get back into recovery and take the proper meds if she is truly bipolar and if she is refusing to do those things she is doomed to fail and will run the crazy train right through your household.
A no alcohol boundary changed my life... it is highly recommended.
