Thanks for all the advice. As for gun's, pepperspray or using violence; this guy is a war-veteran (yugoslavian civil war), more familiar with all kinds of ways of hurting or killing someone, so i'll be no match for him in a fight, i suppose.

He's definately the craziest person i have ever seen, and dangerous. For instance; when the twin baby's where born, he called a nurse a 'gestapo-officer' because she told him not to shake the baby's, and his condition only deteriorated further, since.

Being a single mother is hard enough on itself, but this is psychologically almost impossible to cope with, for my sister. I visit her as much as i can, each day. But taking drastic step's like moving is just very hard for her.
