I just don't know what he will do if I kick him out (it's my house, my business, in my name only) I feel soooo guilty I want to curl up and hide,
First, not your problem it is his problem as it will be a result of HIS ACTIONS.
Second, since he is getting his medical help through the VA, IF he really wants recovery they also have a long term LIVE IN program.
You need to take care of you period. Please, since your time is so constricted with the business, stick close to SR. You will find you have great support here, and we will walk with you in spirit.
