My advice is to move on so you don’t have to be lost, broken hearted and confused any more. This woman has been going from man to man since 2007, as you write it, and she isn’t giving you a green light to date her now.
Read Date Out of Your League, [url]https://www.askapril.com/relationship-dating-advice/date-out-of-your-league.html[/url], so you can quickly understand how to win a woman over, and how to know when the woman is ready to be won. This one isn’t.
You may have had great times together, but they’re in your past. She’s dating other people and doesn’t want to date you any more. Move on.
I hope that helps, and that you’ll follow me @AskAprilcom (no dot!) on Twitter and on Facebook at this link: [url]https://www.askapril.com/relationship-dating-advice/date-out-of-your-league.html[/url]. 😀
