HIs ACTIONS, not his words will tell you whether he has found recovery and is working a recovery program.
In the meantime, sounds to me like some Alanon might help you also. Protecting him is not helping him. When he starts kicking the door, call the MPs, you do live on base. He is also going to have to explain all those "holes in the walls" to his CO.
These are the CONSEQUENCES of HIS ACTIONS. You cannot protect him from that. Those consequences will help bring him to his personal bottom sooner.
Please try Alanon, and yes there are meetings on your base, of that I have no doubt.
Please keep posting here and let us know how YOU are doing as we do care very much.
You are correct, your son should not have to see what is happening, and should you separate, the Military will make sure you get an allotment for child support.
