How to trust someone again who has consistently lied?

Honestly? The way I see it, if they have consistently lied, they can't be trusted. That doesn't necessarily mean they can't be in your life anymore, things just might not ever be the same.

It is very difficult to trust someone after they have lied consistently to you. It will not happen overnight or easily. To build back up the trust, the person needs to prove to you that they are capable of being honest. The person who has lied needs to be aware that it is the right thing to do to tell the truth, regardless of the consequences. Open and honest communication is the very important.

Personally, I would work on forgiving the individual who has broken my trust, as it would be difficult to trust them again if I haven't. I find it takes time for trust come back once it is broken. Be patient, spend time together, build new happy memories and eventually trust will come back.

Question is, If it is a good idea to trust somebody like that. Why would you want do trust somebody who betrayed you in the past? I highly recommend to consider this. However, if the person wants to change, you can give him one more chance, but be carfull. Don't trust him blindy and absolutely. Sometimes it is good to check if it's true, what the person is saying. It is easy to lost someone's trust but it is incredibly difficult to get it back. And the person should know it and understand it.

you can give him a second chance but beware that he lied and he did it once he will do it over and over and over you can give him a second chance but just becareful and take precautions

Urgh, thats a difficult one. It really depends on how much you cared for them and if you have the patience to find out what eventually got them to start acting this way. I personally think everyone deserves at least a second chance in life.

The lies may seem innocuous and innocent but the reality is that this person feels lies are acceptable. He or she may lie about being late coming home or say they did something that you needed done but in reality didn't do it. No major lies about infidelity or money but a pattern is being established where lying becomes second nature to the truth. Stop making excuses for the person who lies to you over and over again. He's not going to change and you can't expect him to be truthful

Perhaps... You don't. You may find the determination to choose to trust them, but whoever has "consistently" lied to you clearly hasn't earned your trust. If you want to still keep them in your life, I'd advise giving them a 'last chance' to show that they can be trustworthy; but frankly, don't let yourself get stuck in a bad situation just because you are too kind to let them go, or too afraid of losing them. Your friends/family/partners are only going to be worth keeping around if they respect you.

It is difficult to trust someone who consistently lies or has manipulative behavior. This person will need to prove over an extensive period of time that have stopped their lying ways. There is no reason for you to trust this person until they have a pattern of reliability. It's okay not to trust liars. However, if the person is making an honest effort, they can empathize with your position and will understand that you cannot trust them until a period of time has passed in which they have been truthful. Consider what compromises this person can make with you in the meantime, depending on their lying habits. For example, if the person has lied about who they speak with, are they comfortable showing you their phone from time to time? Trust goes both ways, however. Do NOT snoop on someone who has been lying to you. You too must remaining trustworthy to the other person. If you cannot think of any compromises, ask the other person what they would be willing to give up to prove to you that they are being honest from time-to-time. If the other person is unwilling to compromise on anything, let them know that they are making it even harder for you to trust them. Don't tell the person, but think to yourself how long you will wait to assess their trustworthiness again - a month? six months? How many more chances are you going to give this person - one, two? Try to be open-minded in this time if the person has expressed that they want to stop lying. Keep your boundaries. If the time comes and you decide you still don't trust them, let them know you'd like to take a break from interaction. If the person crosses their chances, let the person know they have lost their last chance and you'd like to take a break from interacting with them. You deserve to be around people who you feel comfortable with, with whom you feel you can trust, who trust you in return. These are just options and by no means are a path to success. Trust is a difficult thing and will take a lot of communication and self-reflection to sort out. Good luck!

It depends on what they lied about and what the relationship was. If it was a small lie may just be aggravated, If it was a huge lie it will just take a lot of time before you can trust them again.
