Primrose, I commented on your first thread, written the day your H suddenly announced that he no longer loved you. He was going to withdraw the offer made the previous day on your dream house. I recall how he coldly walked away from you whenever you approached him to talk. He was so cruel.
I had wondered about you, and was sorry to later read that H had been cheating. He was willing to shatter you and the children for 4 drunken shags/ego-boosts.
You have written about your determination to empower yourself with counseling, an expanded social life, and fitness. Has H done any work through individual counseling to examine and change his character traits and behaviors that led him to lie and cheat...his weak boundaries, poor coping strategies, and sense of entitlement to pursue illicit sex/ego strokes?
Has he come clean regarding what he told OW about you, your marriage, the children, and the promises he made her?
His tone-deaf desire to attend the Christmas party is utterly appalling. It shows a fundamental disregard of your suffering and the prioritizing of his selfish wants over your feelings.
He inflicted deep wounds and doesn’t get to dictate your schedule of healing. You are in the early days of recovery. Many relationship counselors estimate that it can take 2-5 years for trust to be restored, and that is when the cheater makes every effort to help his/her partner heal.
I agree that you need to rethink your decision to stay with this man. You know what he is capable of. His recent behavior is another betrayal of your trust.
