Man some of you guys here are fucked...Rage face bro, judging by the sound of things she wouldve been interested in you early on however things went stale quick and she eventually lost interest.
The pen was not too personal, that was fine, but my advice to you is as ahlungor bro said. Ask yourself if you really like this girl. If the answer is yes. Take a step back and give the hoe some space, stop being obsessive. I know its hard but you need to restrain your over excited ass. Give it about a week or 2 then reset and try again but this time dont come across as desperate. Play it casual and cool and get the girl. Just be yourself and be natural.

Never ever get dating advice from a woman. They are fucked in the head and dont know what theyre talking about half the times. Good luck rage face bro
