I'm tired

I fell in love with my "sister", but she already loves another guy.

We met 2 weeks ago (I think), and I thought she was single, the way she was holding me and the way she spoke to me, I thought I would finally have a girlfriend. but it was on a Saturday morning that my entire dream was destroyed. the following week, I still had a chance to have her as a great passion in my life. want to guess? Well, she took some time out of her relationship, and started wanting something more with me. again, my dreams were completely shattered, they came back in less than 24 hours.

I feel tortured, loving a committed girl, who calls me her brother. I lost my hope for better days.
