Couple days ago, I talked to a girl at a college party and we agreed to workout together because she wanted to learn how to weightlift properly. We exchanged numbers and she made a note to herself on her whiteboard. We agreed on sometime today, but I have yet to receive a text from her. I normally go workout at 7pm, which is a few hours from now.

In situations like this, do I

a) Not respond at all and let her text me first, even if that means she potentially never does

b) Text her before I workout something like "See you at the gym at 7pm"

I'm asking this in /r/seduction rather than /r/askseddit because this type of situation tends to happen a lot (at least in my experience). Girls would make plans with you and seem excited, but end up not texting you first.
