ok first the family thing does not always work that way. I still have a good relationship with W family. Yes i dont get invited to all of the things i would have before but i still see them and do things. Remember they will be a part of your life forever witht he kids.
As far as your other idea. I know you think you will get flamed for that here. Well I am not going to do that, but i dont think the timing is right. Let me explain.
you are in the midst of this move right now. I dont think anything is going to stop that right now. too much has happened with house etc.. I also think it is not the right time for two other reasons. One is you need to let her get away as she believes this is what she wants and needs. the other is you need to have some time for yourself not being so co dependent with her and give yourslef some growth and also her.
I would say after there has been some time then you start feeling it out and if you still feel it then do it. I am kimd of in that area right now.
Take that for what you will.
