It was an eye opener for me to read on this forum about those who have alcoholic partners who are also narcissistic. 2 different issues, one making the other worse i would guess. Maybe it is just selfishness that really stands out at a time like what you were going through.
No , my stbx AH would not be like that in a situation that you are going through. He more likely would feel guilty for some reason and/or he would make sure to let me know not to worry, he would do the right thing and take care of everything while I couldn't help. He would want me to concentrate on me and the baby.
PS: Will be praying for you, pregnancy and your family!!!!!!!!
