She has been told by the doctors that she is bipolar-she is just in the last month starting to take meds for this problem.
By the way par4me, you can "become" bi-polar or have a "bi-polar split", from leading a double life. You have to do a lot of lieing and keeping track of the realities.
If the person comes out of it, IE: no need to lie or lead double life the "bi-polar" symtoms dissapear.
So perhaps your wife coming home and being good, and you provide stable loving foundation for her and she will be fine and so will you.
