8, bottom line is that you have absolutely way of knowing that W will do what she says...ever! That is the reality you are faced with. Now, you can continue to try and work with her and jointly agree on what is best for your children or...or what? What other choice is there? Would it be better for your D to see her parents in ugly confrontations or refusing to speak with each other? Would it be better for her to hear that Mom (or Dad) is a liar? I think not. Of course, this is not happening presently but you also don't want to create a situation where that could come about. I know personally how anger can quickly bring about results I always deemed unlikely! If W violates your agreement then I would call her on it repectfully but then work with D as best you can. The reality is that seeing OM will not be a life devastating event, emotional as it might be for her. Also, if D is 14 does she not have the right to choose whether to see OM? Maybe discuss the options with D (if the time is right for that)and tell her you will love her no matter what she chooses to do but she needs to do what is best for her, not what is best for Mom or Dad. Help her make good choices. Just a thought that at some point may be relevant! Take care.
