you know, 10 years later, and a remarriage to OW and no feelings for eachother on either of our parts, we still, somehow immediately inform the other of an illness/death of one of our family members. I guess because at one point or another, these were people that were a part of our lives, and in some cases, are a part of our child's life (but not all). We give eachother sincere condolences and rebalance the kid schedule if needed. But that's about it.
It's 3 years later and she could still trigger you with kissy faces. Do you NC because it's a way of possibly leading her back to the M, or of you NC because it is what you feel is best for your own good?
