my ex is verbally, emotionally abusive.controlling , volatile, possessive,erratic, changeable,with a drink problem .we seperated 18 months ago. he had added himself to my tenancy ( housing association) when we got a bigger flat just before i gave birth. he moved out, took himself off the tenancy and got his own h.a flat . he still sees this as 'our' flat, and says anywhere his daughter lives is also his.he refused to leave the other day when he became verbally aggressive and threatening. i said i would call the police, i think he gets off on controntation and arguments from his patterns over last 4 years, so i didnt call them.he seems programmed to cause chaos, drama, and conflict .he is gifted in starting arguments like no one i know. what are my options legal and otherwise if this happens again and when i move to a new house, which i dont want him in, to stay in, or have any sense of his. just mine and my daughters. can i stop him from entering with a court order? and if he doesnt leave what are my options as i suspect this is the start of worse things in the future. abusers usually get worse ?!
