Ok so I had a crush 5 years ago (I still have a crush on her). I asked her out one day and she said yes even though she was already dating someone (weird right). So I was really excited to go out with her then about 2 weeks after talking to her I seen her kissing a guy and she said she had been going out with him for a month. I was like WTF but ok. So we don't really talk to each other anymore. I like some things she puts on instagram and she likes some of my things. It's been 5 years and I still have a crush on her and I dream about her everything night even though I know she's dating someone I still have a crush on her. They got engaged last month and I still have a crush on her. Do you have any advice on how I can move on?
