Is it normal to broke up because of his sister?
I had been living with my boyfriend for two years and i think we were in love and most of all went pretty well. My boyfriend and his sister haven't seen each other for 10 years. Strange things started happening after she came to our house...they could walk on the street holding each other, he could hug and touch her in intimate parts of her body. She became all world for him. He even went to Victoria Secret to buy underwear with her. I decided to talk to him about that strange affectionate relationships, but with no results, all he did is threatened me two times. First he asked me if I know that he has a knife in his pocket and second time was when he showed me the card and commented that it can cut between my fingers. After that we broke up... I have so many questions about what happened but my general question is How his tender feelings to his sister could bring aggressiveness to me (his girlfriend)? Thank you.
