Let the games begin, Moonchild. Someone may be trying to shake you up psychologically to get you off guard. This could involve using intimidation to make you less assertive or manipulation to get you to make a certain choice. As long as you don’t let your guard down, you’ll remain in control of the situation. What you need to consider, though, is the reason for this person’s apparent betrayal or unusual display of meanness. There’s a reason for it, and although it may seem otherwise - it isn’t about you. Don’t take any efforts to control you as a personal assault. Something is going on in this person’s life on a deeper level.
