Busting, I think we all feel that desire to reach out more especially when we have had a positive interaction. i can not say what is best for you, you need to feel comfortable with your choices at the end of the day..
i know for me that i have stepped back into more darkness.. first i saw everything as her fault, then all as my fault, now i am seeing both of our roles.. but since i was most recently blaming myself, being more honest about things STBXW did, especially during the break-up, brings up some anger, confusion and disappointment, and i do not want to interact with her from that place...you have a tougher time due to your beautiful children.
as brit says, i have taken her off the pedestal.. i think that is an important step. it sounds like you are dong that too.
i like LITB's post about giving him space to miss you.
