Welcome Cali. Also I am so very very sorry for what brings you here. This type of thing is absolutely heart breaking.
As the others said, you are getting in between alcohol and an alcoholic and the results are pretty predictable; however, no matter how predictable the pain will be excruciating. If you can, find an alanon meeting. You might need to try a couple different meetings before finding a good fit.
Take care of yourself. Let us know how you are. Many of us have been in similar situations.
