Block him, and any friends who take his side. Poisonous controllers never change... But you can, you can change to being a strong, intelligents woman who knows her own worth, and understands alone for a while is better than being with a complete manbrat. Take time to (re)build your friendships, get some counselling if you are struggling as you may need help breaking the cycle he has tried to impose on you. If he comes crawling round stand tall and tell him to get lost. If he refuses to go call the police if you have to. If he keeps phoning block him or change your number. Good luck, might be hard for a few weeks, you will get flashes of doubt but stick with it because it's so much better when you come through to the other side.
