Younger Brother + Older Sister = BEST

My(26m) older sister(33f) took care of me for years. She always made sure I was comfortable and well taken care of. I felt like I never had to lift a finger when she was around. So I haven't. I am living with her now and she works 60+ hours a week. She has been paying for my college, car, clothes and everything else. She bought me a car to drive around, she gave me money for my own apartment and let me keep her large house. I do not have a clue how she works so hard and make sure I am comfortable. She has this **TERRIFIC** boyfriend who is an absolute gentleman and is so nice to me as well.<br><br>&#x200B;<br><br>In return, I have been stalking her. I get to watch her in the shower and several other places. Sometimes I will even hide in her room and hear her with this **NUBB**. I really can't understand why she doesn't leave me alone and enjoy the luxury of life with her hard work and never having to worry about money. I am not thankful of her kindness and support. I also feel disgusted that she never tells me when she is with her boyfriend when I am home alone.<br><br>&#x200B;<br><br>I just met her new boyfriend last week. They were sleeping in her room. I was in the bed next to her so I could watch her. I wanted to see what they looked like when they were together. I had a flashlight and was shining it at them until her boyfriend woke up and he yelled at me to leave. I told him that I was not leaving because I could do what I want in her house. He left saying he was done with her.<br><br>&#x200B;<br><br>She was upset. She said I needed to leave and she didn't want me anywhere near her. I am starting to regret my actions now.<br><br>&#x200B;<br><br>What should I do now?
