I recently got engaged and told my sister. She didn't seem so excited but of course she is my maid of honor. Whenever i bring up wedding stuff she ignores it or bring its about herself. She never asks me anything about my wedding or fiance. I am really hurt because my sister is my twin and we're best friends. However I am the caring sensitive one who loves to be in plans and my sister is only concerned about herself. I don't know how to handle it because when i try to talk to her she laughs or gets mad.
