I hope that YOU and your kids enjoy your Thanksgiving and Christmas Holiday,, ukiah.
I feel that it is unfair of him to try and influence the gatherings and plans that you and your children enjoy.
Any relapse that may or may not occur is beyond your control and definitely not caused or influenced by you.
Be supportive but draw the line at enabling.
I hope that your AH seeks some kind of a support system; it could truly benefit and enhance his sobriety.
