I agree with vapo and you try to low ball her to get her out. I think you have to wave the proverbial white flag and work on detachment and yourself.
I lived with my ex for 16 months prior to her filing for D. Not ideal but it was 16 months of seeing my kids everyday. Command respect and show her your best self. Now in the time to become the person you want to be. If you want to kick your porn habit then work on kicking it.
I'm not going to lie your, next few years are going to be challenging but you will over come it and come out the other side.
The truth of the matter is that life can be really $hitty sometimes. It's about how you respond to it is what counts.
