I feel like I want to give you a really profound response but brain is bad today 😂 so instead I wanted to say congrats on your sober days and I'm sorry you had to go through that with your ex. That must be very difficult. My partner was in your position (though thankfully not to the same degree) and worried about my drinking but I'd just push him away any time he brought it up. Now I see it for what it was and I'm glad he stuck by me and tried to get me to stop even though that change had to come from within (it's a bitch like that).
You did the right thing for you mental health and thinking of her in similar turns to your own problems with alcohol is probably the best way to perceive it as both are bad for you and best avoided.
