Met a few girls from dating app.

A few tips would be:
Hot and cold interaction happens commonly, it takes two to tango. Gradually improve how to read the mood, keep yourself occupied with yourself interest outside online dating and swiping, she owes you nothing.

Found one that tick most of my boxes, i dropped all messages with other girls and paused the dating app for a time being (to have less distraction). Created genuine interest and being present after a couple of calls and messages. Went out date- she surprise me with gift , lucky i got gift as well.

End of the day is regulating own expectations and emotions, knowing what you want (whether its increasing date/bed count, meeting the one, direct sales/ property agent). Have your own self-worth.

And yes, I agree timing, luck and plays a role, if she is keen, progress is easy.
