I can see where you are one of the people that come to the board and get advice ignore it then come back a week later and tell us all the mistakes you made and now things are worse.
I sense the making of a great Hollywood movie where she’s at the airport with the yoga dude going to Mexico and your hurdling airport chairs and you get to her gate just before they board. You pour out your heart and soul to her and she pushes yoga dude away and falls into your arms.
Just to be clear 1st that is totally a joke. Please don’t do that.
The best thing for you to do right now is completely let her go. NC what so ever. Take time to mourn the break up and heal. Absolutely start reading books like the ones I recommended and understand what women are attracted to in a man.
In the event she ever contacts you again (do not wait for her to), if you are available tell you would love to see her and then hang out have fun and hook up. If she brings up just being friends, tell her you have no interest in being friends.
Simple in theory but my impossible for most here to implement.
