Well the detaching part is right. The problem is you can't just say I am detached and then you are detached. It's a process and it usually takes several months if not years. There are people on this forum who are not detached at all 7-10 years later.

"Yeah, in the morning she was sulky, probably thinking about our sitch. Later, she was trying to attempt like everything is normal. Wanting to chat whilst I'm playing with my younger daughter. Trying to engage me and the older kid with jokes. It's hard to DB here because there are child things everyday."

This entire statement shows lack of detachment. If you were detached you wouldn't even notice her you would be to busy playing with your kids. It's almost impossible to detach during IHS so that is why I am trying to convince you to move the process along as quick as possible.
