My husband is in another country and we have been apart for several months. His behavior has changed a lot in the past year - he used to be so loving and now he is so abusive - picks on me and does his best to chase me off. A year ago during one of these separations due to me doing his immigration ( thank god he was refused) he started being obsessed with wild, kinky sex ( threesomes, group sex) and for a whole year this is all he talks about. In the past week he has suddenly become really cool and distant and rational - usually he was so angry because I didn't come right back to him because he was abusive. He now talks about how we aren't a good marriage and how divorce is normal. This behavior is happening right after the visa refusal came. I have tried to hard to find evidence when I was there last time but the only thing that was strange was that when he moved into our new apartment before I arrived, he threw our 2 bathrobes into the washing machine - said they were dirty. He is usually a slob. Also found women's slippers which he said were from the former tenant. He also took one phone call into the bedroom. Is he cheating ? I have asked him so many times and he denies it. I need to hire someone to follow him.
