I think she is trying to dictate the terms of how things should go, its a sense of entitlement and arrogance and with these 2 character traits you cannot have a successful reconciliation. Reconciliation comes from a place of humility and this is definitely not it. Try to detach and stay emotionless in any interactions and fulfill your duties with your kids to the best of your abilties. It seems like shes still in the mode of either you take me back or i find someone else mode.
