Is it normal to feel like i can't move on from this girl?
I'm a 23 year old guy, and I fell deeply in love with my best friend (a girl). She had feelings for me at one point, and I was too slow and stupid to notice and she got over them. Well wouldn't you have it I finally realized that I was in love with her. I told her how I felt, but I could tell she didn't have those feelings anymore, so we agreed then it would be better to stay best friends.
However a short time ago I was being a supportive friend and she confessed that I was the only guy that was ever nice to her and that actually likes her, and then she admitted that she kinda hopes maybe one day we'll end up together when the timing is better.
I'm wondering if its normal for me to hold onto the idea that maybe one day we'll end up together? Or is it better to try and move on and let time decide what happens? I'm deeply in love with this girl and I just don't know what to do, any advice is greatly appreciated.
