I'm sorry, I can't assist any further, this thread has become too triggering. I will however leave you some questions:
.
Have you looked inside yourself and been honest about why you're staying? And no, not the lighthearted stuff you tell yourself to make it ok, like 'my bestfriend's still in there' bcoz you KN0W he's not. HE TRIED TO KILL YOU, not very friendly now is he? I'm talking about YOU... Why do YOU stay? Are you dependant on him? Are you scared of being alone? Are you scared of leaving?
.

You want to save your marriage but at what cost, your life? I honestly hope whatever the cost, it's worth it.
.
I'm sorry for being harsh, I just don't understand why you don't value yourself, your life.
.
God bless
