Hi Ericar .
At least you have made a start by telling your husband about how you feel and what your thoughts are with the baby on the way and how his behavior is affecting you , is good that you are not financially dependent on your husband and if it came to a needs must situation then you would at least be able to afford it .
Reality is your husband still has too many excuses against seeking help , not AA for a start , having to go to meetings etc whereas, if he is really really serious he would be willing to do anything especially for you and the family and that unfortunately does not seem to be the case . Fact is that one can stop drinking if they really want to they do not need to go to meetings and ''then stop '' if I were you ''even if you do not really want to '' tell him in no uncertain terms that you are really really serious and you are not going to take any more of his unreasonable behavior , he is selfish and self centered to the extreme and cannot envisage life without alcohol.
Who knows maybe going to Smart will bring some hope to first and foremost himself , because if he keeps on feeling he is hopeless then he will remain hopeless , but you cannot put all your cards on this making a difference, I certainly hope it does but you need a contingency plan because you know deep down that this cannot go on .
Ericar please keep in touch cos who knows maybe by sharing you are getting rid of some stress rather than bottling it all up, so stay in touch , thinking of you .
Regards Stevie
