Maybe the pain is all you have left with the person. Let it go. You will not heal in a toxic environment.
Trust takes years to build & seconds to break.
There is only betrayal when one “loves” with conditions and expectations. There are no strings attached to pure love, no expectations, otherwise one’s love is actually a trade, a type of barter, that states, “I will continue to love without limit but only if you behave according to my expectations.” Is that true love or conditional love? With true love there is no betrayal and there is no letting go because there is no clinging. The greatest gift true love confers is freedom for the other person to be exactly who they are. ~ Joseph Rundle
