It's been going on for about four years. Every time he goes to rehab he just ends up back on the street it's really getting depressing. He has gone to jail 3-4 times now and rehab 3 times. He broke into our house once a couple years ago and tried to open a can of beans with a knife and destroyed our kitchen counter. Just 3 days ago he walked right into our backyard and stole my bike. I really don't even know if he can be helped at this point it's just awful. When he is sober enough to talk to he just isn't even the same person.
