I think is too late , one again , this happens because of the lack of kino at the beginning , remember you have to wait a little bit to express your intentions ('m talking about 3 to 4 min , not 4 months

) but anyway , I guess your in LJBF and the only way you could get out of there is with little escalation of kino maybe , get another girl to try to get her jealous ... But I think this is over man your stuck in LJBF zone ...
I jsut noticed that the most common problems in the community are One-itis and the LJBF .
I will make a big post talking about this (one-itis and Friend Zone) and explaining how to avoid it and how in the ase of one-itis a few ways to get rid of the anxiety and all problems that come with one-itis.
But at least for you Brick ; I think you should use this girl as a Pivot cuz she isn't into you. Only as a friend.
