Is it possible to forgive a lie to a loved one?

If a loved one admits his mistakes, does not deny the fact of a lie and wants to understand how to change the situation, then the lie can be forgiven. But if he continues to behave as if he is not to blame for anything, and accuses you of being too picky and suspicious, then you should think: are you on the way with this man? The reverse situation: what to do if you are caught in a lie? To begin with, answer yourself the question: “Why am I lying to my beloved”? What drives you every time you try to hide the truth and come up with an excuse? Fear of breaking up a relationship? But won't the consequences of lying be worse than what happens if the fact of lies is revealed?
