Need To Detach, But How?

[NASCARDaddy]

What are you going to do different, from now on? What will be your "stop sign" that you will notice it is time for you to leave the convo and come back to it later, if necessary?

And... how are some ways you think you could do that?

That is where I get hung up. I can always spot where I made a mistake afterwards, but I have a bad habit of pushing too hard and too far, even when our convos are going good I can wreck them by pushing for too much or trying to get her to agree to more than she is willing to give at the time. Just a month ago she was open to R talk, but I pushed too far, too fast and now she is completely closed off from that. I don't believe that she will not ever be open to it again, even though she says that is case. However, I could certainly push her to that point if I can't figure this out ahead of time.
