About a year ago I asked a very very shy/reserved good girl out twice after she was showing massive IOI's as a shy girl would.
When I asked her out both times she went really shy, blushed and went tight lipped.
She rejected me twice those times which really confused me because after that she still seemed likes she liked me.
I am really really good at reading body language and I managed to pick up on these subtle hint i.e constantly checking me out, being really nervous and shy around me then when I talk to her she smiles and lights up etc..
There were many signs and we eventually went on a study date and the circumstances suggested she really liked me.
She rejected me for the second time when I tried to get a second date after the study date.

(basically I asked her out and she said no. I built some rapport with her and after a couple of weeks we went on a study date. After the study date I asked her out but she said no)

She went out with her best guy friend for a couple of months a while after she rejected me for the second time and the IOI's stopped. She remained really nervous around me.

When she broke up with him she started showing huge IOI's and I hit on her but didnt close as I dithered but then she started seeing another friend.

I think she is still seeing the other guy but I am not sure. I can still tell she likes me.
In about 4 weeks I will never see her ever again and I am not sure whether I should try again or not?

Right at the beginning last year she was eating out of my hands and I cocked up. I either came on too strong or I was being a pussey (when I think back it is cringe worthy)

This is defo the girl that got away and I have got so much regret, she is everything I want in a girl.
I know one thing for certain and that is if I was half decent at pick up I would have her by now.

Do I try again or let it go?
Shall I just accept that it will never happen?
