I'm sorry that you find yourself in this position. I'm also so sorry for what your daughter is facing.
I have to honestly say that I don't understand the action of facilitating her journey abroad and cutting off her funds, as opposed to just "disabling" the trip.
It just seems vengeful. And a bit controlling. You have been betrayed in a horrible way. But your actions seem a bit like...as if to say, "I may not be able to control your decisions, but I can punish you in a particularly harsh, premeditated way".
I also don't understand the constant reference to (my words) "taking her to the cleaners" financially. This all just sounds like basic, raw, revenge.
Don't get me wrong. Her behavior is reprehensible, and she is going to pay the price (no pun intended) by losing your love, and her marriage. This "that will show her" attitude seems unnecessarily harsh.
I am thrilled for you that you are so successful and financially comfortable. I'm sure you have worked very hard for what you have. But if you have so much, why is it so important to be so bent on "cutting her off". This is your daughter's mother, and even though you seem to have a lovely relationship with her, and have handled conversations with her very well, I fear your actions may have gone too far in her eyes, if not in yours.
I must say that I agree with what Bigger has said - mostly regarding the significance of sending someone off across the globe unprepared. And to seem to enjoy it so much.
Also, I have to add that I want to support you in your pain and your journey to survive this horrible situation...which you did not ask for or deserve in any way. But there seems to be a big focus on spite here.
And I love this site. I spend way too much time reading and posting here. And I am a bit surprised at the cheers and "Way to go"s from the majority of posters.
I read here that some of the "cheering you on" comes from others who, looking back, wish they had handled their experiences differently than they did. I understand that. I do. I guess I am just more comfortable with stories of...."What crazy stuff did you imagine you would do to your WS?" than with this level of actual consequence. And the joy it seems to bring so many. To be so joyful at the demise of someone's life. There are lots of WS here who faced well deserved consequences for their choices, but they are still people, and do not need to be completely vilified.
I wouldn't blame you in the least if you absolutely do not consider R. She is going to lose her good husband, her marriage, her stability with her daughter, and her extent of lifestyle. She deserves that, if that is what you choose.
But all this trip drama seems simply....I don't know......mean.
I realize it is an understatement to say that I am in the minority here, so I will stay away so as not to spoil the communications.
I just wanted to offer another view. I hope my opinions have not been offensive. That was not my intention.
My best hopes and prayers for you and your daughter through this hard, hard experience.
