You are getting a lot of good advice here. Go back to your last thread and read that and this one again.
Anger is a good thing if you listen to it. It is a signal in response to a hurt. What is the anger telling you? Listen to it.
She is not hurting you - you are hurting you.
Learn what you must do to improve you.
She wants to speed things along? You cannot control that. If you fight, the ropes get tigher and tighter until you strangle yourself.
So, instead of aggression or frustration, be assertive. Show her the man you are. A man does not "give in" or "delay" - a man respects her wishes, supports her when he can, and works to get the fair deal for him, his kids, and her. A man takes care of family - even if she is pissing all over it.
A man makes the best of the hand he is dealt.
Yes Mark, it sucks. And it will take time to get past it. What she is doing is wrong - but she sees it differently right now.
Show her anger and aggression (little boy behaviors), or show her giving up and rolling over by letting her "call the shots" (wimp behavior), and it just confirms her low opinions of you and the R.
Instead, show her a man in control of his emotions and in skillful control of the situation, with the best interests of the family at heart (mature man behaviors) - that is your best and only chance for her to reconsider her direction.
