How to trust someone again who has consistently lied?

You can't trust that person anymore. That person has betrayed you - not once, but over again. You should just let that person go and find a person who actually cares about you. It sucks, but it is really what you should do. If that person doesn't care enough about you to be honest with you, then he/she is a horrible friend.

Trust is a strong thing that once broken may not be fixed. If you truly want to trust someone, you must be the one to make the first motion. Tell them you do not like being lied to and you want them to be honest and take baby steps from there.

If you haven't confronted such a person about their consistent lying, you should do so. Really get to the bottom of why they are lying. Are they unhappy about something? get to the bottom of that issue and be sympathetic. It also helps to let them know how much you want to trust them and, while avoiding provoking guilt, let them know how much their lying is affecting you.

When someone has constantly lied, if you really care about that person, I believe that he/she must show that he/she really care about you... then, after some time, if the intentions are good, then maybe you can trust again that person.

When someone lies to you it can be really tough, but when they lie to you over and over it can be even harder, because you it is hard to trust anything they are saying. You have to talk to them and hopefully they can work on gaining your trust back. Let them know that the lying is hurting you.

Someone who has proven themselves to be a consistent liar can only be trusted to do one thing: continue lying. Everyone deserves a second (and a third) chance, but when a pattern of behavior becomes impossible to ignore any longer, it may be time to consider removing that person from your life.

Let go of trying to control people and always hearing the truth for them. Live for yourself, be yourself, care about yourself, love yourself. Others, they have their own lives and agendas. Listen and hear what they say, but don't take it all in.

Trust is a funny word in my experience, 5 letters one syllable but what does it actually mean? Most discussions on trust involve things about what another person will or won't do in a relationship. "I trust him because he would never cheat on me" Or, "I trust her because she always has my back." But what happens when someone falls short of what we expect of them? Through many hard fought battles with trust I now think trust is not something outside of myself dependent on whether another person will or won't hurt me ever (or again) BUT on my own ability to overcome deal with and resolve that hurt if the person does hurt me. We have no control if/when a person hurts us, especially if that hurt is unintentional. The only thing I can control is what I do if it happens. This is the way I use to determine if I am going to invest any more time and effort into repairing the relationship. Especially if it is a repeating pattern I need to make sure I have enough emotional reserve to deal with the aftermath if the person hurts me again. If yes, I can work on the relationship, if I don't have enough emotional reserves or feel I can't survive another blow I might reconsider the relationship.

Forgiveness. You have to forgive. You never forget but if you must or want to be ok with it, forgiveness is the best way.

Sometimes people can regain our trust after a period of time--over that period of time, we might learn to trust that person again after he or she follows through on promises they have made. Depending on the person and your relationship with them, it may or may not help to discuss your concerns with them in a non-confrontational manner.
