Excellent post Ziemo,
She knows exactly what buttons of yours to push to get what she wants skubus.
It's called, "power of the pouter".
She is mentally abusing you as you know how weak us males are.
as she keeps telling me no one else would want me
My advise is to get not only professional help but an open minded female friend with benefits.
Prove her wrong by taking the sex out of the equation in your relationship with her.
When she bats her eyes at you the auto mode will be off and the manual mode of your big head will be doing the thinking.
Just vision to yourself the look on her face when you tell her, "No thank you, I have lost interest in that."
Games Over !
