OP, I used to be married to an alcoholic.
There are a few facts here that will hurt to realise, but you’ll never move forward without them.
His primary relationship is with drink.
It doesn’t matter what you do or don’t do, he will still drink.
He will not stop drinking until the consequences of his drinking become so unbearable that giving up the drink makes itself clear to be the better option.
He will never come to that realisation while you’re with him, providing food and shelter, looking after him, supporting him, providing a comfortable space where he can indulge his relationship with drink.
Your children are seeing everything. They’re seeing him drinking all the time, they’re seeing you putting up with it, they’re seeing him be rude and disrespectful to you.
Because your children see all these things every day it is normal to them.
The things they consider normal are the things they will default to when they are adults, because with normality comes comfort and security, even when that comfort and security is harmful to them.
OP this situation will never improve because of two indisputable and immovable reasons.
- He is an alcoholic. No matter what you do or say, however hard you wish, however hard you try, however much you cry and plead and beg with him to stop, he is an alcoholic.There is literally nothing you can possibly do or say that will change it, or convince him to change.
- You are enabling him. Moaning and pleading and begging will not work, and while you persist with things that do not work you are letting the situation continue. Asking a rock to get out of your way is not going to shift it. Unless you move it yourself it will remain in your way for ever.
I know this is hard OP, I’ve been there, and I know you feel responsible for him, like he would get worse if you kicked him out, but look at all the above. What is more important in your life, his ability to drink in comfort or you and your childrens’ right to a secure and happy home?
Can you tell him to go and stay with a parent, or a friend? At least if you can get him out of your hair for a bit you’ll have a bit of time and space to think it through.
