Kenny,
Welcome to SR!! There is a lot of good information on this forum. I can see that you are at your witts end with your alcoholic wife. I stayed with my AXH for 34 years and finally couldn't take it any longer. It took me about a year of 2 times a week open AA meetings, 2 times a week alanon meetings and nightly SR to get some what healthy. I educated myself about this horrible disease. All the support I received gave me the strength to do what I had to do.
You are on no time frame to make the decision to leave. Actually, Alanon doesn't recommend you to make any major decision for 6 months. Read around SR, there is the new to recovery forum, alcoholic forum and of course friends and family plus the alanon meetings. Once you have a grasp of what has been going on in your life you will be able to make the right decision for you.
Hugs my friend, you have reached out to get some help, and we are here for you!!
