What are some body language that a manipulative/ abusive person use to control and isolate you?

One thing that I have noticed is that they give you almost no personal space, stand or sit really close to you, and stare into your eyes. You feel pressured and end up giving in to their demands.

Another thing I noticed is that when you turn around, you catch them giving you the angry stare, like they want you to feel guilty about distancing yourself from them, or about the last "No" that you gave to their demand.

Is there anything else I should be cautious about, or does it take knowing the behavior of each individual to see the pattern?
