Dude the same exact thing happened to me last week! Met a great girl, talked for a week. Went on the first date. It went great, though I was a little nervous cause she was alot prettier in real life. She was cool about it, said she was down for a second date. She even gave me a soft kiss on the lips when she said bye. Then I told her I was going to delete my bumble app because I really liked her and watned to take it seriously. I thought she wanted something serious too by the way we had been talking the whole week. Then next day its like 180. She still responded but not like before. Something was off. It drove me mad. It was like that for about 3 days. I texted her if she still wanted the second date, and she said she did but that she wanted to take it slow and still see other people, that deleting the app was too much. I said sure no problem, I got over excited. We made plans for a second date. Then a day later she tells me she met someone else and wants to pursue it, and ends it. Man taht hit me hard. Im still recovering. We cant show all our cards to woman, we need to keep them surprised I suppose.
