I was where you are at a little over a month ago. My son was scheduled to go into a long term rehab. When the morning came, I told myself. I will not wake him up. I will not ask questions like "are you packed" or " are you ready to go". I left it up to my son and his HP. I just knew that if he didn't go, I was going to drop him off at a men's shelter and say goodbye.
I went about my morning and was pleasantly surprised to see him getting ready. I was pleasantly surprised to see his bag packed and by the door. And I was pleasantly surprised that he said "I'm ready to go now." I knew that I wasn't going to take him up there if I had to do even one smidgen of convincing or cajoling. Luckily, I didn't have to. As always, actions spoke far louder than words......it's just, in the past, I wanted so desperately to hear specific words that I would overlook the actions.
Hang in there. Time will reveal more. It always does.
gentle hugs
