Is it too late for us?!?

Back in high school which was a few years ago some stuff happened. There was this girl and I’m pretty sure she had a crush on me. She would always stare at me and got really nervous then I came around. I am also a girl. We went to a really conservative school but she made it very obvious that she liked me. The way she stared at me was insane and she would try to talk to me and get close to me for stupid reasons. One time she saw me walking and went the other way. A lot of stuff happened. I secretly liked her bad but never did or said anything. She left the school and I graduated and it was too late. I have a boyfriend now and I really do like him. However I still think about her and stalk her page all the time. I can’t help but Imagine what my life would be like if we got together. She is in college now and everyone I look on her page it seems she’s made a lot of new friends and isn’t as tomboyish as she used to be. I’m almost 100% sure she had feelings for me. I always think about having sex and doing stuff with her and I can’t control my feelings. My sister is graduating next month so I am hoping maybe she will be there but I don’t think so. I’ve been thinking about her night and day. I know she liked me and kind of feel sad because I wonder why she never added me on social media. I don’t know why I feel this way.
