I am so sorry KAW... you and your D must be having a really hard time.
I agree it does sound bad. And CAW should not be mad-mouthing you to her BF, much less in front of your D. But actually when you described the phone call I found it weird that OM hung up on CAW. Could it be that he is trying to break up all contact...? I may have misunderstood but it did not make sense to me to hung up on her that way...
Take good care of yourself and your D. Will see what time brings... {{{{{{KAW}}}}}}
