I went to the gym today right before a first date and ended up getting the number of another girl who I had been talking to for some time in the gym. She offered to meet later that same day (Saturday), which I thought was a strong IOI. However, I told her I couldn't (b/c I already had the other date lined up) but would be available Sunday. Additionally, she even came by to give me a high five before she left the gym.

Fast forward a couple hours to tonight. 3 hour first date completed - it went reasonably well, but I'm simply not that physically attracted to this girl. So 7pm Saturday night rolls around, the date has just ended, and I text the gym girl if she is free to hang out at a cafe Sunday afternoon. 1.5 hours later, she responds "Have plans, I forgot."

Where did I go wrong here? On one hand, I probably should have taken her up on her proposal to meet same day to maintain momentum, but on the other, I've read not to cancel plans with one girl for another. My plan now is simply to propose a meeting next weekend, but I fear the interaction is already dead.

Where you went wrong is when you texted her and changed your mind. You were too needy. Couldn't you hold it for some other day?

And the girl probably felt that you asked her out as a consequence of your plans getting canceled or something. That's not attractive. What does that say about value? That your plans are not as important as they appeared to be?

Don't assume it's over. It's not over until it's clearly over. Give it another shot with her. Next Saturday.

Well I didn't really change my mind. I wasn't inviting her to hang out Saturday after failed plans. I just texted her on Saturday night to hang out Sunday. I never told her I wasn't available Sunday. In either case, I probably shouldn't have texted her Saturday night. Next time I'll text in the middle of the week for a weekend hangout.

This gym girl is probably a 6, so I feel like I'm getting kind of lazy about tightening my game with her. Would you say it's better to ask her out again on a specific day or just give her a "Let me know if you're free next weekend" type of text?

Oops. I thought you texted her Saturday to meet that same night. So disregard what I said.

In that case, it wasn't wrong to text her. It was a good time to text. Why wait one week? So it's her, not you. Maybe she truly was busy on Sunday.

She was horny in the moment in the gym. In the future, if a girl is horny in the moment. Take advantage of that. If you don't, she comes back to her senses.

Tell her let's meet Saturday. She seems like she's not busy on Saturdays. Wait until after midweek to say it.
