In my experience, women often will feel cornered or pressured to give a guy her number or agree to go on a date with him. You didn't pressure her, it's a societal thing where girls will feel obligated to "give you a chance", as the saying goes. The issue with that is women will then realize they truly don't want to go through with it, so they make an excuse to not have to arrive. It's not acceptable behavior at all and I'm not justifying it, but I've seen this happen a lot.
