I haven't read your whole thread, just the last several pages. Your comment above about seeing him in those clothes hit a nerve as I just did laundry yesterday (for the family) and came across the clothes H wore this weekend to see OW and thought 'I wonder if she knows that all that he is wearing is what I have picked out for him'.
I have no relationship advice but wanted to pass along that one thing that has helped me in moments of weakness if focusing on being the mother that my daughters deserve. Focusing on making them proud, even though they are oblivious to what is going on, and remembering that they deserve the world, and their mama deserves to be taken care of. Staying strong and focused for them helps me to get back on course and then eventually stay on course for myself.
Sending hugs and wishing you all the best....
