I don't see a lot of positive signs from the chick in this text exchange--especially since she's immediately setting up a "I'm busy" excuse--suggesting that you're not the best at gauging she-wants-the-D tells. Giving you her number means almost nothing in 2015, unless she does it unsolicited or with some serious body language, so I hope there was more to it than that. I can almost imagine from your text tone that, in person, you're friendzoning yourself, creating insufficient connections with these girls, and misreading signs.
