Just to add on to what Eric said, and to answer your question in a different light...
This is a little something I copied to my personal archives in the beginning .....
Every time you say to them, "But, I love you," you are saying, "but I want something different than what you want. You want to pull away, but I want you to come closer. I don't really care what you want. It's what I want that's important."
Lots of times men tell their wives, "I've changed. I've changed. Let's get back together. I've changed."
I tell the husbands that "Every time you say, 'I've changed,' you're communicating to her that you have not changed."
"Really? Why is that? How is that? I don't understand that."
"Of course, you don't understand. But what's your motivation? Why are you telling him or her how you've changed? What's your purpose? Isn't it to get your way?"
"Yeah, I want her back."
"That's your way. It's not her way, right now. She said she may consider it later, maybe, but not right now. And every time you say, 'I've changed,' you're saying, 'Give me my way! Give me my way! Give me my way! What I want is more important than what you want. I don't give a hoot what you want."
And subconsciously, she says, "He hasn't changed. He's still the neurotic, selfish, pressuring guy he always was. There's no way I'm going to go back to him, or feel positive to him as long as he is this way."
