What would you call this behavior of a person who first pretends to be nice to you and takes care of you to start with. He continues to do this till he convinces the other person that he is their trust partner or well-wisher. Once this is established, he starts to invade in to privacy of the other person and even tries to take control or possession of everything they may have, or atleast behave as if those things (of the other person) belongs to him. Now he doesn't respect the other person but rather abuses him/her to the extent of forcing them to live up to satisfy his own selfish needs. I am been subjected to similar treatment in past. Please advice.
