I guess Stig forgets that just about every HD on the planet thinks they've done everything but throw themselves into the fires of he!! to communicate how unhappy they are with the state of things...
Since you won't leave....
I am suggesting to you, to GET THE BALL ROLLING... go fck your H. As Stig says, if you verbally pounce on him right now for not initiating, you're going to get one big... "HUH???"
So, get it going again. I'm not so sure why you can't be honest with your H, and in a very honest way, afterwards say to him... "gosh, that was amazingly lame sex after not being with each other for 8 months." Quiet voice. Not accusations. Roll over. Go to sleep.
Try again a few days later. Honestly assess the ENCOUNTER, not the person.
In any event, get it all back into the foreground of his thinking... don't pretend it's great sex. Don't pretend it's the worst sex (if it isn't.)
But you can't deal with the issue... until it is clear in his head what issue you are discussing... sh!tty sex. Not sh!tty man, not sh!tty H, not sh!tty father...
