my ex has done the same thing. It's that exact behavior that has had me calling the police frantically because i didn't know what else to do. Only it was meth induced. He'd sit there and flip out on me and tell me to "give him money" i'd refuse, and he'd forcefully remove me from his apartment. Up until a couple of weeks ago, i hadn't seen that side of him in a long while. I'm wondering if his choice to not call me or anything has something to do w/ the drugs and his bipolar mania. So I know what it's like to go through something like that.
Stay strong.
