How to trust someone again who has consistently lied?

You can't. Unless that person changes. The best predicter of future behavior is past behavior. when nothing changes, nothing changes.

Trusting yourself is the most primary thing to do. Only when we trust in ourselves can we have the power to trust others. Distrust and being skeptical of a person arises due to fear that we are not strong enough. We are scared that the person may lie again and hurt us. Imagine, if we never had any strings attached to a person, if we didn't depend on them, would it really matter what tale the person was telling us or others?

Its hard but you need to have them regain trust. If they constantly lie then it's hard rebuild trust but it could be possible.

Its tough to trust those who have lied. My advice would be for you to always ask for proof in what they say. For example, if they say they have tickets to a ball game ask to see them in person. Otherwise assume that they are not being truthful.

It's hard but loving someone the best thing to do is day by day and babe steps you will get there really

It is a very hard thing to do. I have dealt with a similar issue and the best action to take on is to restart from the very beginning to make everything right an okay.

Once they have lied several times, Its hard to trust someone again. Confidence and effort would be the answer and spending more time with the person will build the relationship and hopes to trust again.

Having them prove to you that they can be again. Example: if you tell them something no one else knows and they keep it to themselves and with you. That is one step closer to earning your trust back.
