CaMom, we had to do that with Rob when he was at the Residential Treatment Center (RTC). He would call us sobbing. Every time. For weeks. Broken record. Same thing with visits. When we would get there he would sob. Endless. Time after time.
ARGGGHHH!!!!!!!!!!!!!!
Finally, I/we told him that we wouldn't talk on the phone if he was just going to cry. And we wouldn't visit if all we were going to do was sit with him while he cried. When I had that visit conversation it was because he was sobbing on the phone the day of the visit. I/We had had enough.
So interesting how a little over an hour later when we got there he was BEAMING from ear to ear and we never had to sit through his tears again.
Stay tough. Your son knows that in the past he has brought you to your knees. You need to prove to him that YOU have changed, just like he needs to prove to you that he is working harder and changing as well.
You can do it!...and if you feel weak, go out to dinner with husband and don't answer the phone.
No mercy!
