OK - I would just look inward and assess where you are at emotionally and determine if you can actually have these types of conversations with your W and not read into them or have them impact you. Based on what you type you still seem to be very much attached to her. If that is the case IMO these type of back and forth conversations can still keep you attached at some level. I know early on I was not able to carry on such lengthy conversations via text. It literally was yes, no, thank you or no response at all until I felt my confidence returning. In time maybe you can but I question whether or not you can at this juncture.
Only you know what your true motivations are. When you typed our you text exchange I initially thought that is good. Then the last several sentences about how you felt, assuming the worst, etc. made me feel you still have not let go which based on the text messages feels like it puts you right back into the cycle every time you have an interaction with her.
Maybe I am wrong but it is what I observe based on what you type. Again really ask yourself if seeing her and having these interactions with her stir things up, and stops your forward progress or do they help you?
