Dr has put him on Lithium. It appeared to help him greatly, but then was taking some steroids for infection and pain meds which really set him off.
He appears to be able to swing quickly and frequently from one extreme to another, from loving to mean and hateful within an hour. We are living in same home with plans to marry so I have seen this up close, also he will not cut ties with ex-girlf-still texting and phone talks. One day he says he will not have any more contact with her and the next he does. Not sure if that Bipolar or just selfish.
Boundaries are a problem for me. He has crossed alot of them but out of fear of losing him I allowed it. I am very strong willed so it is very difficult to allow myself to remain silent when he is saying mean things.
