Hello guys.

So I was talking to this girl over tinder. I did a soft close, then went for her number

She gave it to me and we talked a little over WhatsApp. On Friday we agreed on going on a date for the next Monday. When Monday came, I sent her the location for the place where we would meet up but she said she thought we were going out on Wednesday (I offered Monday and Wednesday back then but we said Monday) . I told her that I already planned Monday so I couldn't do it on Wednesday anymore (not true but I didn't want to look overly available). I told her to get back to me when she had a better idea of her schedule and she agreed.

I'm pretty sure she won't reach out because she would probably just forget about me eventually.
I have to be the proactive one, I probably should have not given her all the power.

What should I do now? I was thinking of reaching out myself next Monday , but I don't know if it would be best to call her of just text her. If I do text her, what text would be ideal to reignite her interest?

Thanks
