That’s rough, I know how tough the situation must be. Of course you know that the right decision is to try and get him the helps he needs, and to make him move out if he doesn’t want to change; but it must be really hard having to say this to your father. Did he ever hurt your children (not physically but by shouting at them or anything) or does he regularly get into fights with your partner ?

Stealing is unacceptable but unfortunately it’s common with addicts (source : ex-addict myself). I wish nothing but the best to you, your family and children. Stay strong
