Couples therapy is NOT a last resort for your marriage. It could be the very thing that keeps you from ever contemplating a “last resort” in the first place.
“In relationships [with a low negativity threshold], couples allow each other to complain, and work together to constantly repair the tiny issues between them. In such a case, couples don't bottle up their feelings, and little things don't end up being blown completely out of proportion”. - Hannah Fry
