So sorry you are hurting. You have received some wonderful wisdom here. Relationships do change once recovery begins. Sometimes slowly, sometimes in a heart beat. My RAH is 2 1/2 years sober, but his family are all heavy drinkers. My alcoholic nephew tackled my 22yo daughter, broke her collar bone, dislocated her shoulder and put her out of work for two months and she's still in physical therapy. We were very close to his family for the last 33 years, and we haven't heard a word from them and it happened two months ago, not even to check on our daughter.
I found this quote and read it daily. "God often removes a person from your life for your protection. Think before running after them."
Let them go...
Hugs and prayers for peace.
