I really feel for your friend, it's soo hard to deal with.
You're mum's answer is soooo typical. My mum, who no longer considers herself a dub and wants nothing to do with it say's the same thing to me when I try to talk to her about how hypocritical the whole DF'ing thing is.
Give your friend a huge hug for me and tell we're all there for her.
Give her my email adress if you want. [email protected]
I went throught the same thing got df'ed just to get away from an abusive husband, and no nothing happened to him either.
