When do u know that you are done in your relationship

Dear Brooke / coaches , i am in a bit of struggle here – i want not to react to my husband behaviour and be compassionate instead but have truoble finding the thought . It cost me intimacy , at this point its just akward .
The reasons are irrelevent , i learned that its my thinking not anyone is fault .
I want to be ok with not being together id it vomes to it , i actually dreaming of being in peace and quite – i am worn out by morning yelling abd screaming .
How can i start loving him again and then peacefully go seoarate wats if i decide to ?
