BND...I am so happy for you and your family. You have been through so much in the last few years. I see how your MIL will have to eat crow now and as you've said on my thread, they will try to conveniently forget all they have said and done and will try to get back into your family. I do think you will have to set some boundaries. Their involvement with your M will only be to somehow find a way to break you up again. How can they be so cruel and then pretend like they are happy for you. A snake can never be anything other than a snake.
Would you mind stopping by my thread as I have a question for you and would really appreciate your input.
