Update - there was a misunderstanding of both me and sibling when I could stay at WAW siblings house and it resulted in drama. Long story short, I stayed in a hotel for those days. But from witnesses, WAW was visibly angry that I would be staying somewhere that she did not approve of. Sibling sided with me and will let me stay there as much as I need and within an hour WAW was ok as well with it. Somewhat surprised by how angry she got over this. I guess I am wondering why she is getting so angry now anyway. I basically said I would not fight her if she files and am willing to pay child support and follow a visitation schedule. Any reactions?
