Re: how to find the courage to file
If he has moved on to another woman, picture this:
He comes back in a week and says "let's work this out. I want to be with you".
Do you think you can really go on like that? Can you ever trust him? Will you even forgive him for the mere action of leaving, let alone being with another woman?
This is the person who promised to stay with you and be your protector. Not only he failed to do that, he actually attacked the very core of your vulnerabilities and left you bleeding.
There's your courage.
