An emotional manipulator is the picture of a willing helper. If you ask them to do something they will almost always agree - that is if they didn’t volunteer to do it first. Then when you say, "ok thanks" - they make a bunch of heavy sighs, or other non verbal signs that let you know they don’t really want to do whatever said thing happens to be. When you tell them it doesn’t seem like they want to do whatever - they will turn it around and try to make it seem like of course they wanted to do it, and how unreasonable you are. This is a form of crazy making - which is something emotional manipulators are very good at.
Rule number two - If an emotional manipulator said YES - make them accountable for it. Do NOT buy into the sighs and subtleties - if they don’t want to do it - make them tell you it up front - or just put on the walk-man headphones and run a bath and leave them to their personal theater.
