I am sure it isn't easy for you and I can understand your frustration but, like you said... package deal.
This forum is for people going through divorce and all the aftermath, etc. You probably have a good point but maybe there is a forum for those of you who are married to the people who went through the divorce. My ex is with a woman who writes absolutely every bit of documentation for court and probably looks everything up for him as he's basically lazy. She has to involve herself in everything. We do not have minor children. It's pretty sicko. One small example.... When we first separated (he had put all of our company money into her bank account)he gave me money with a note from her (in her handwriting) insisting that I sign for it - MY OWN MONEY. Another example - I found his garage door opener that he had left in my son's car and dropped it off (left in his mailbox) and the bitch tried to have a peace bond (restraining order) put on me. She used to continually call my lawyer and I could go on and on.
My own personal experience has definitely made me have a very low regard for people who butt into matters that should clearly be between the two people who were married/had the children. I have heard the excuse many times that the new wife/girlfriend is just "doing the research" but I don't believe it all of the time. Sorry but that's just my feeling.
