I would not discuss and make plans with her. Take it slowly. She said she wanted be to out on her own, so that is what she should experience. Why should she be given the vacation of a lifetime if she has left you and living separately? Unless she has contributed financially upfront for the trip, in which you could offer her money back. Play it by ear for a while.

But as Melissa said, if by then you feel the two of you could get along well enough, then choose whatever you think best. I believe she will "expect" to go.....b/c WAW's cake eat! They want to participate in family events whenever it suits them, but if the LBH gives her too much attention, then she accuses him of pressuring.

Start now, in everything concerning her, having no expectations. Make it a practice, or you will constantly be let down.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
