From what you say, it looks like you and your husband are at a crossroads. The man you love or loved is still there but for the time being and maybe for longer, he is unavailable to you. This is a consequence of addiction. You don’t have to stay with him. Putting your emotional health first may mean it’s better that you separate. But a word of hope here too. Family recovery is possible. Some families find a way through. But if you choose this route, what you will have will certainly be different to what you had before, because the past can be understood and worked through, but not erased. That’s the misery of addiction. Get help, be clear with him and most importantly, don’t let this become the legacy against which the kids will always be measuring their lives. They need to be able to love their dad, just as much as you want to, but for very obvious reasons, are finding difficult to do right now. Going forward as a family is possible, but this needs everyone to understand what their role is in the addict's recovery, which is absolutely not picking up the pieces for him, no matter how tempting.
