Hey
No apologies needed, that’s what this forum is for.
Reading your post it sounds like you know this is a problem as it’s affecting you, your family and your relationship.
No one can diagnose him as an alcoholic bar himself unfortunately, however based on what what you wrote it does seem that is the issue.
Unless he recognises this is an issue and wants to help himself there is not a great deal you can do
Do you think he would be receptive to the idea of getting help?
