Lisa, I have been watching this thread, and want to say this as gently as possible... You must know that this, right now, is the The Most Dangerous Time in a domestic violence situation.
I know that helping her is difficult, and worrying, and in some ways all-consuming. And that you need support. Posting here may seem like a safe way to get that support, but it is so easily searched, and her husband is likely searching.
May I suggest, also, that you take down the posts about it? Even leaving them up for a short time heightens the danger for both the family in question, and your own family.
Through college and after, I worked at a domestic violence shelter. The stories we lived there are frightening, and very, very real. We were trained not to discuss the situations, and for good reason. If we needed support, a trusted friend, in person, was the way to go - but putting anything on the internet would be considered very dangerous.
I'm very concerned for the family involved, and also for your family. Retaliation is not unheard of. You are at risk as well. Your children are at risk.
Unfortunately, you are very recognizable through your posts, and, through you, this friend will be as well, especially with some of the details posted.
Not trying to offend at all, and I hope you take this in the spirit it's intended: concern for the safety of all.
Hoping for the very best outcome possible, and that everyone is safe soon. :grouphug:
