Before we start I didn't start anything with her. I don't even talk to her nor do I keep in contact with her. So last week we were on a family trip. We slept in villa. So one morning, it was like 3 in the morning, I went down in the kitchen to read and have some alone time. A few minutes after her sister came down a started talking to me. Now I don't like her sister because of the horrible things she said and did to my wife and overall she is a horrible person. I was giving her short answers. Then she sat next to me to see what I was Reading. I told her to move. She didn't. She then RUBS MY ARM AND MY CHEST. I feel so bad because my wife doesn't know😞😞. What should I do?
