Calyx, it doesn't matter how often you tell him to seek help - he will only do that on His Terms & when He is ready to do so.
He will have been in a blackout when he hit you - hence the rolling of the eyes at you now. He knows that something happened but he won't remember what it was.
He says he is listening and not drinking - you won't be able to take his word for it for long - you'll soon be checking up on him, looking for hidden booze, following him to the shops, timekeeping.
Yes, by all means tell him that you are going to Al Anon - but you are going for Your sake, not to find out how to stop him drinking.
Please please try Al Anon. It will help to clear your mind and to get some perspectives before you make any major decisions about anything.
Never threaten re leaving - they know every trick in the book to keep that house of cards standing.
CAT me if you need any advice about what Al Anon is about.
Please please don't be panicking about your age and using that as an excuse to keep trying for a baby - you need to understand why you really must not do this right now with this person. Bringing an innocent into this madness that you have right now is the worst thing you can possibly do.
He is not stepping up to the mark with just the two of you in this relationship. Once you bring a child into the equation his drinking will really spiral out of control - take it from me, because I have been there as have many of us on this thread .
If you can bear to, try to read both Part 1 & all this thread. You will learn an awful lot and most importantly, you'll realise that you are not on your own.
