Actually.. this is happening when she needs to end the convo. I've tried in the past with mixed results ending the conversation first. Over the last 2-3 days though.. if she's talking to me and for whatever reason needs to go, she apologizes several times and says the words above.
I simply say "It's fine.. I'll talk to you later"
It's been working so far, so I've stuck with it.
In the early days, she was attracted to me being a little harsh. Now it seems she is attracted to my kindness (although I will not allow her to use me again). The fact that she wants me to confide in her and she wants to confide in me is a big step I believe.
We had that a "little" in the early goings, but she whacked me with a bat afterwards. Now if she wants to swing.. it won't hurt as bad. It will actually be a little anticipated.
