You need to be there, validate what needs to be validated, be by her side, confront if you have to. She needs to do the work. N/c is imperative.
My OW tried to contact me twice last week. It´s been more than three years from our last encounter. I didn´t answer her mails. But it triggered some anxiety on me. My fantasy demon whispers she´s waiting for me...I can´t follow that path. All I can do is hope the best for her but I can´t break the n/c rule. Three years...and she still has the power to set my mind into some spin...That´s what Sandi says: the fantasy life. The sooner n/c is get the faster the fog will disappear. But you need patience because it´s her process and it takes time.
Be strong, confident, consistent and amoafwl. Facing reality, eyes open.
