I can’t bring myself to do it

I know that my marriage is over. I have packed my bags so many times and he has talked me out of it that things will get better. Tonight I packed and left while he was at work. I get 2 Miles from my parents and answer his call because he won’t stop calling (it’s an hour drive away) and I again let him convince me. So I drive back home another hour in the pouring rain.

Now all I want to do is scream and yell at him. I know it’s over. But how can I get the strength to complete leave the next time?
