Hello Mum, No you are not being unreasonable. It is your choice to live how you want to live, and that right now is free of an ah. He should be grateful that you are even willing to try and work things out.
It is his choice to live in that home with alcohol, he knows there are other options. If he truly wants to be with you, he will do whatever it takes to get you back.
He is making you feel guilty, and that is not acceptable. You are a strong woman and it's impressive how you have taken a stand and stood by it. Don't back down now, your demands are reasonable. If you back down now, he will keep pushing for more. Soon he will say he only wants to drink on Saturdays. Then he will change it again to only drinking beer. Then it will be; if you really loved him you would see that he can't stop drinking because he has a disease.
You do what you have to for you. You and your needs are important and you will not tolerate anything less.
Good luck to you,
Stacy
