Well honey get ready for the roller coaster ride if you let him live with you. everyone wants to believe their addict or that situation is different but in reality addicts share many of the same characteristics.
Addicts who want help stay clean. Don't ever let an addict in your house that is using you are nothing but an enabler for the addict! Wake up, addicts steal and lie I don't care how good you think they are and they bring drugs in YOUR house! In some states you can also be charged with possession! Never ever let someone who is using in your home, there are half way houses and shelters he can stay at!!!!
