@ poster,

you have wooed a girl for over a year
and she hasn't said yes at all? Im sure you have bought her gifts and stuffs too which she probably took but still said no??
I think you and I both know the answer to your question,
Leave her alone. she is truly not interested. If a girl is a little bit into a guy, it wouldnt take her half that long no matter how hard stone headed she is. Girls are not that complicated.

I feel a bit sorry for you though cause you seem to have wasted a lot of time which you could have invested in someone better, and who is more into you, and who will appreciate what a genuine guy you are.
Dont worry, no matter how much it hurts that she has rejected you, move on and find someone else.
I dont see any changes in the future on her part if it took that long, sorry

Goodluck with the next search
