As the son of an alcoholic, I can tell you firsthand that alcohol is her first love right now, not you or even her S. She still loves and adores him, but the addiction is first in her mind. Visitation is hard in this case. My dad didn't bother contacting me for months, so it wasn't an issue when I was growing up. I would lovingly tell her that she has missed dates, and ask her what her plans are for future visits. The past is the past, and it can't be changed. Forgive her for missing the dates in the past.
