My sister turned on me when I lost 100 pounds?

I lost a 100 pounds and my sister started to start fights with me. She did not want to go out with me and everything I said she would disagree with. She became combative and mean. She stopped liking me because I was not fat anymore. How can a sister be so cruel? She’s my older sister. This hurts me still to this day. How do I move forward? Over the years we have tried to make it work but she always starts arguing with me. When I was extremely fat nothing could make her mad at me.
