ok so i've been into PU for a while now, and i got pretty good at it, sure i've had some good times and some funny one night stands and some rly good ones lol

but i have a friend, shes rly good looking and smart, and only a yr younger then me, we always talk and we always have a good time and we are extremely comfortable wit each other
, the thing is, im good with meeting new girls and getting them to sleep with me, but this isnt some random girl, shes a very good friend of mine.. and honestly i think im falling in love with her...

so my question is how can i turn her into a long term gf? i rly dun wanna screw this up, so any advice would be good guys =]
