Caroline woke up on a new day. Still trying to cope with the recent downfall of her relationship with her husband. She admitted to herself that she's been crying a lot lately because she felt saddened by the crumbling of their relationship. From her point of view, it's already impossible to reconcile with her husband.
Things will never be the same again.
They can no longer go back to the things they used to be.
Something has been broken the moment they have sexual intercourse with other people. They broke each other's trust completely and it killed her. It's so hard to swallow.
Now she realized how anger and jealousy can push a person to madness.
It's now clear that their marriage is on the rocks, and this might be the last blow that would dissolve their marriage.
