You ex has started the hoovering techniques, prepare yourself for the Grand Hoover which is basically him coming round banging on your door, possibly kicking your door in, causing a massive scene, doing something violent and terrorizing all of you. There is a lot to read about the grand hoover and how to manage it and protect yourself:
