I just wanted to pop by and send some hugs.
I grew up in a household where there was one parent who had an alcohol dependency. The choice was given, their children or the alcohol, they chose the later. As a child you think its normal, you do see the things the adults don't know you've seen (maybe not it all but enough) and peice together it when your older, or at least I did.
Please don't blame yourself, you are not "boring" you just have expectations of what is acceptable to you.
As a child of a parent who is an alcoholic, I can say removing them from the household when I was youngish (9) did help me, I saw a different household to what I always considered "normal" grew my own expectations of what I wanted my household to look like and what family unit I wanted, yes my home is not perfect, not the dream by a mile, but we have no shouting, more laughter than I ever knew and no alcohol, my dc have never seen myself or oh drunk. I may have a small baileys (and it's mini) at Christmas with my dinner but it is not a regular occurrence in our home and not something expected regularly.
I understand you worried about grandparents etc, but from the bottom of my heart please, they are not your responsibility to protect, if they shun your children, yes it will be awful but an unhappy mother, children being hidden from the truth will do more damage to your children in the long run. If your husband isn't able or doesn't want to accept help, then is this the life you want your children growing up with as "normal" and have the possibility of accepting for themselves when they are older and get partners? I am forever grateful of the big step my parent did for me, it was hard really hard but more than doing it for me, seeing the life my dcs have now fills my heart with so much pride that we both did it together to build a new future for the later generations.
Sorry for rambling on I don't usually post but it is something close to my heart.
