Anyone dealing with a spouse or partner who is an alcoholic?
My husband definitely is and does not admit it. He is what most call a functioning alcoholic. Without going into too much detail, as he has gotten older it has gotten much worse. I’m 63 years old and I just want peace but no way to get out of the situation, financially and emotionally. I know that sounds like an excuse but I’m retired, not by choice and have health issues. How do you deal with this if you are in a similar situation? 🥺
