Ballast, I can relate. There was a period of 5 weeks where the WW and I were intimate and working on things and I thought I could pull her away from the OM. When I saw her increasing communication with him, I fully detached 3 weeks ago and now I am in a similar situation to you. Typically complete avoidance before and after the weekends that she spends away every night. Two kids here that I care for and little regard for them or me. I am moving on so it doesnt bother me but my youngest is tired of her pestering him about where I am when she is away. The days in between she usually is struggling with her emotions and I can see she is hurting and suffering some sort of mental anguish.
She was scheduled this week to speak with a therapist but after a one sided text argument this morning, canceled the appointment. At this point she will either get help or will have a full mental breakdown and end up in jail or committed.
It is very hard to deal with but like I said I can relate. This person changed on me overnight and I do not recognize her. Prayers to both of us that this works out the best it can.
