OP here.
Yesterday I called my friend to meet up for lunch next week. She had this to say, basically it boiled down to this. That she felt no matter what we should just except her DH actions and behavior because that's what friends do, and on and on about how selfish we were all being excluding them because of how he behaves. So she is more than aware of why no-one wants to socialize with them. Which really hit a nerve with me. I said he is your DH, and therefore he is your problem. I went on to say that where is it written that you have to put up with someones spouse or partners bad behavior, and rudeness, and overall lack of basic manners just because your friends. NO where. I said that I had way to much on my plate to worry about all this. I said I hope things work out for you, and I have to go and good luck to you.
So that's that!
I really feel that she was way over the line.
Thanks for all the advice, it really helped.
