Hi Mamamidge,
I'm glad you found the site and sorry for the sadness that brings you here. This is a supportive community of people who have walked in your shoes, and will walk alongside you as you become emotionally resilient.
Getting a diagnosis nailed down can bring some relief, however, it's also not uncommon that an official one never comes. What matters is how well you learn to take care of yourself and your kids while mitigating the conflict and effects of the mental illness as best you can.
I understand the tendency to enable and appease to protect the kids. It sounds like you know that enabling has limited short-term effect (if any) and potentially disastrous long-term effects.
How old are your kids? Do they know their dad is alcoholic? What is their relationship with their dad like?
Once you get yourself into a place of emotional strength, it gets easier to not take some of the behaviors personally. And learning to set boundaries can help protect yourself from some of the more impulsive and damaging actions, like spending too much, drinking too much.
We're here for you. You're not alone
