I would try and look at it as a blessing.
I know when I was drinking I did not want to be around people that were not drinking. It made me uncomfortable. My ex recently called and he was going to stop over but he blew me off. I was hurt at first but I understand. He does not want to spend the afternoon with someone sober.
It hurts when people that we love reject us because we have changed ourselves and our life style. I feel in the end it just a way of letting go that maybe we were not ready to face, yet here it is staring at us. I needed to accept it and move on. I am not angry, it is just life on life's terms.
It is God doing for me what I could not do for myself. I could not break that connection, so he did it for me. I feel a sense of peace and relief about it now.
