Q&A How Do I Hang On?

I was together with my mate for 12 years before getting married. She cheated religiously. And lies about it to this day. We discussed her cheating prior to getting married but 3 years in she was having a year long salacious affair in parking lots and hotels all around our house; even bringing our 1 year old out with her. She canceled what would have been our first vacation since having a child to invite the AP to the conference instead. After D-Day, she lied denied and blamed me for 5 months. Then piecemealed info for the next 7. Only admitting to what I have proven to her. She has 0 empathy and is constantly accusing me of not letting us move on, just get over it, etc. She is also a compulsive liar. We signed up for EMS Weekend but we won’t make it until the March date. I just can’t take it anymore. Help, please.
