I (27 M) matched with and talked to a gorgeous woman (27 F) for a week and half before our date. After we agreed to a date activity, I gave her my number to take her off the app and vibe elsewhere. She kept talking to me on the app without acknowledging the phone number. Sent her the date place details and we took it from there. Date went well. I flirted, made her laugh a lot, teased her, got to know her, etc. We hugged at the end of the date.

I got home and our conversation / our match was gone. I was hurt, not gonna lie. We vibed damn near effortlessly. Could she have saved my number from our chat and plans on texting the next day, and the app communication was now unnecessary? I am asking all of this because I don't think I did anything wrong. But who knows? Any help would be great. Thanks.
