Re: how to get her back???
Hmmm this is a bit much. It's not a good idea to be with someone that isn't over their ex. And the fact you are still talking to her while she is with him makes it worse. She's getting her cake and eating it as well.
But the feeling of losing a woman you were with to an ex is a sucky feeling. So the desire to know that you can have her back whenever you want is a powerful one. You want to have that control and I get that. I just hope that you don't really get back into something serious with her while she is still not knowing what she wants. You deserve better than that.
And that's exactly what you should tell her. That you want a woman who knows what she wants. That isn't conflicted. You have to make yourself a challenge. Use Cat String Theory.
Now this could swing either way. If she is serious about trying with her ex then it may work against you. It's about a 50/50 chance so use your best judgment to see if this is an option you can afford.
I'm not sure what else to tell you other than don't let her have her way where she has both of you. She either gets 100% of you or 0%. Talking to her while she's still with her ex just lets her know that you are essentially ok with her doing you dirty and just up and leaving. Most women respond to men of challenge, not men that allow her to treat them less and walk all over them. Hope this helps and good luck.
