If you can not trust them, you can not love them.
Love is not an emotion or a feeling, but an action. If they are breaking your heart, then their action shows they do not truly love you, adn you need to move on.
You must get past your feelings and emotions.
True love is this....Actions which cause feelings and emotions.
NOT THIS....feelings and emotions -> hope the actions match
You will never be happy until you discover that the actions must come FIRST, then the emotions adn feelings will follow.
