Here's what I think..I think you need to decide what is best for you and those kids..Only you know that in your heart. I also think you need to let her know you won't stand in her way of going to OW, now if she wants to go but the kids stay with you until something is on paper and legal..I also think you need to let her know that she will not push you into this haphazardly..looks like she's in a big rush. d'S with kids take time.
