@Robert28 Women need two things from men, financial stability, and lack of emotional attachment. So let's say she falls in love with you and you pull back and she keeps chasing your validation and you are financially stable, you got her by her tits, she's in love with you and ready to nest. This is going places actually. You said your relationship wasn't going nowhere, that means either you were not financially stable enough for her, or you showed emotional weakness or as she perceived it to be that way.
However, most likely she did not have feelings for you, since she thought she could do better, and you pushed for relationship. She saw nice guy in you and used you as a provider.
Now you dumped her... Great, she needs now needs to validate several things so that she don't feel damaged. Since dumping her ass is the opposite of emotional weakness, she needs to validate your financial stability.
Anyway, your ex does not know what she wants, which is same as knowing she can do better. I'm sure you're not dumb enough to give her money, she won't be giving it back just for the turmoil she could have from it. Tell her though, your new girlfriend might not like that and send her picture of you and a chick with the biggest titties you have in your rotation, so that she sees you can do better than her. It will destroy her, she might even cry.
