Madi,
I relate and sympathize.
I was a drunk for so many years and I quit because I realized I would die if I didn't.
I didn't quit for my wife or my son. I quit for me. They say otherwise, there is resentment.
I believe you know the answer in your heart. There are folks here that will give you their opinion beside me.
If it bothers you enough, if you are suffering because of a drunk, you can change it. Dealing with a drunk or drugged person is dealing with a physically and mentally sick person.
If your addict is the bread winner, that could complicate things dramatically.
I was the bread winner. My wife would ignore me when i would over do it. I believe she figured I would end up drinking myself to death. I deserved it.
You are in a good place for advice.
Others will chime in soon.
Thanks.
