I know how hard it can be to give up a friend you've had for so long a time, I had a similar circumstance happen with me; with a long time friend, and it was very difficult, like a divorce, or in some ways a death. I still havent gotten over it. In this case, with my friend, she shunned and rejected help and friendship from her closest friends, when her husband died of cancer. I had been one of her best friends for almost 30 years. She became suspicious of everyone and their intentions after he died, thinking everyone was after something from her or some inheritance from him. It was really sad and sick the way she treated everyone that tried to help her. So for my own well being I had to completly take myself out of her life. To continue to try and have any kind of relationship with her was a real threat to my soberity, and it intensified my problems with my bipolar/manic depression. My therapist even recommended, I sever my ties with this person because she felt like the relationship was a threat to my mental well being. So sometimes we have to do what is in the best interest for everyone, and for our own self, and well being.
I hope everything turns out for the best for you, I'm sending my prayers

to you and your friend. Love Bonni
