Give yourself a break for a bit and just stop thinking about her/M/D. Go get a massage and take a walk on the beach with your S.
You have done such a wonderful job enhancing your parenting skills and your R with your S5. You should be most proud of yourself.
Hang in there, dude, and do something loving for yourself. What would you do for a very dear friend in the same boat? Do that for yourself. And remember what you are "for" -- not what you are "against". It will help you stay focused and positive for YOU.
