"Our relationship is perfect besides this" THIS is huge!! This is something that will always come first before your childern, you, your home, your job, his job, your families. See, to an addict, and your husband is an addict for sure, he will lie, cheat, steal, anything to get what he wants and needs. Not to say that there aren't people out there that get clean and stay that way. But I want you to know that most of the time its a long journey to get there.
