:angel: Traci, I experienced this very same thing when my difficult child was in jail. He had been in longer than your son before I started hearing it, tho. Yours has been in less than a week? Mine was in for about 4 months before he started sharing his thoughts about God.
I will tell you this: After he started praying, things changed INSTANTLY. I mean his whole attitude shifted from Blame to Gratitude and Humility. He had Huber priviledges, and he began going to AA Meetings. Within a month of that, he landed a full-time job. He remains a steadfast employee there, over a year after his release.
YES, remain cautiously optimistic. STAY detached!!! BUT, now you can allow yourself a glimmer of hope. Careful, timid hope, but hope all the same. I also did not allow my difficult child to come home, it was a moot point as he was already employed and had ample funds for an apartment to rent, etc. But I believe I still would have stuck to my guns on that one, and I think you should, too.
Peace
