I am facing a problem like I can't able to deal with. My boyfriend's sister knows about our relationship. She is a stubborn type of girl. Even she can't see anyone?'s happiness. He has two sisters. His elder sister's nature is good. at least she never disrespect anyone. But his younger sis creates conflicts between us. If I asked that why r you doing this. She used so much insulted words for me. Then for 1 time I am. Just like that I have to answer her with ironical words. Bt. I control myself for the sake of my boyfriend. I told this to my boyfriend but she supported her sister and instead of taking my side he said she is very immature to understand anything you should understand. If you r having any problem then you can leave me. I know everybody loves his family. No brother can listen anything for his sis. Bt y he is letting me down before her as I am stranger for her. Instead of her bad deeds he supports his sis. And even told me that my sis is far better than u.Due to her dis type of nature I hate her like hell and even don't want to see her face ever. What should I do.
