Few points
1. Something that began with Haram is bereft of any barakah and will always end terribly, especially when both of you "know" it's haram and thus no ignorance is involved.
You wouldn't like someone doing this to your sister, remember that as you do, so shall it be done onto your sisters/daughters etc.
2. Talking to a women for 5 straight hours demonstrates tremendous low value to her, she knows you have nothing better to do in life and as a result all interest she had in you dissipated quickly.
3. Women are programmed to follow and not lead, you programmed her to never initiate first through your 'actions' and she is simply following it
When it comes to women you presume she is already heavily attracted to you and you simply lead through your actions only, if you presume anything else, you set yourself up for failure.
Never! Ever! inquire about her opinions or emotions for you, it demonstrates to her your off low value incapable of leading her, only the insecure care about what other people think of them, women in general are insecure, the last place she wants to see this disease is in you.
Don't despair! every one of us has made these mistakes and much worse, as always you live and learn in life.
