Tell your partner the truth sometimes. But tell the real truth, the facts. Not “I love you (I don’t love you)”, but “I think I love you (I don’t love you)”. Or, better yet, tell “I think I love you, and perhaps it will last for some time”. As a result each of you will be in good shape. The truth does not free anyone, it is nonsense. The truth nothing but binds a person more. It especially binds those who believe that it exists.
