Sister took me to see Harry Potter - she is sooo good looking now

I felt a pang of jealousy when I learned my sister 22F is dating a guy. I'm 19M and have been in love with her since I was 12 or 13. I used to pretend we were married and we'd have a little family together. I'd find myself fantasizing about her and me engaging in sexual activity. <br><br>When I turned 18 I knew I had to get over it and accept that we can never be the way I wanted us to be. It's illogical and outside of societal norms - I'm well aware of this. <br><br>When I got into my early 20s I accepted that I was in love with her and decided to move on from it. I had a couple relationships, went out with a couple girls, dated one for 8 months. They just weren't my type. <br><br>Last Saturday my sister and I went to see Harry Potter because she wanted to on my day off. I picked her up and when she got in the car I was just in awe of how good looking she is. Her hair is not as long as it used to be. I've always wanted to hold her hand, caress her hair, and look into her eyes. <br><br>I felt so special having all of her attention to myself. I wish I could be in a relationship with her. It all feels so natural - we just click so well. I feel like we'd get along so well in the long term. <br><br>I know it's wrong. She's dating a guy now and I do feel a little bad that his girlfriend is so attractive to me. <br><br>After the movie I dropped her off at her apartment and she gave me a hug and a kiss on the cheek. I felt so happy.
