John, pal, bud, amigo...lol

, I had this same concern with my NOW friend Emily (care to read into that go to the last few pages of the "Prayer Request Thread"), that she would stand me up. She never did; actually, she was mad at herself for not getting into contact with me since she was so busy.
Nicole, does she have busy life, i.e., school, job, POTENTIALLY (as in Emily's case) a young child to take care of? If so, give it some time. It is possible she just got so busy (that is what Emily told me) that she forgot about her social life slightly. You know what I am saying? Sometimes people get so busy they forget that there should be time for relaxation!
I don't think she will stand you up!
I think you know this already, but I learned that when someone stands you up they don't contact you, period. A couple times, Emily and I had something planned, and then a last minute (or hour) thing came up. She simply called me to post-pone to a latter date. Things happen.
