not sure about this.....
might be true....
maybe becasue you take the closeness with him/her for granted...
won't give you exciting or nervous feeling while being with him/her
by the way.... how long is "too" long... and how accquainted is "too" accquainted.....
i am pretty sure if i had a childhood friend who i still contact now..
i would definitely want her to be my gf.....
cause she knows how crappy I am.... so there is no pressure staying together with her...
