Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
Second, do you think your mom and husband would be open to some kind of family counseling? I don't understand why she would have so much anger towards you. Is it something to do with you wanting to remain close with your dad after they divorced? Some kind of resentment for not taking her side? I mean, I don't know what kid wouldn't be upset with their mom in those circumstances.
Your husband is the only one who can make the choice to deal with his addiction. And you certainly have a choice to see that through with him or not. But I hope that you know you are worthy of a loving and healthy relationship. It's concerning to me as well that your mom would take his side when he's doing wrong to you. Wouldn't a mother want what's best for her daughter? I'm sure you know, being a mom yourself, how you would move heaven and earth for your children to be happy and healthy.
Anyways, it sounds like all these problems are very deeply rooted. Some from long ago, some more recent and they're all melding together and causing a lot of friction. That's why I suggest family counseling as a possibility, even one on one for yourself to help give you some empowerment in your life.
Take care!
