Sorry to hear that you cannot contact your daughters-I know that must be very hard for you, but I agree with everyone here, and say "Stay the course"
I do not know your ex, but I do know mine...... and although my ex was not happy with me, she seems more worried about me NOT being happy with someone else(American also)
Strange feeling isn't it, to finally have someone who is willing to sacrifice their own happiness, for the sake of yours. Your Friend James
