Hi Open,
I'm sorry to hear that your husband used. Try not to future trip ( forever is a very long time). I don't know what the future holds, but I do know that you can make the decision to be ok, regardless of what your husband chooses.
There is always hope and hope is not a bad thing. Expectations that rely on another's choices can get you into trouble.
Stick around, there will be others around to soothe your soul.
