Thought provoking question.
My mate an I had a very good relationship for many years. Eventually alcoholism got the better of us both.
That being said, other factors come into play on so many different levels. The following is my truth:
1. I got involved with my mate in a way that was, I believe, contrary to the will of God.
2. My own repentance and conversion led to our breakup. My quitting drinking was part of this.
3. I still love my mate profoundly, and trust in God that eventually we will be involved in a different type of relationship that pleases God. Whether this will be in this life or the next, I cannot say.
I believe forsaking an addiction does not necessarily mean forsaking a person. However, our free will comes into play. Only if all parties involved pursue healing and sobriety, can there be any lasting relationship.
