OTOH,
Just leave it alone! Do not send your xh anything. If he were truly coming out of the fog, he wouldn't be calling you when he's drunk. He would be calling you when he was sober. Just let the calls roll off your back and if he calls and you don't feel like picking up the phone, then don't.

Let it go.


Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
