I lied to my Girlfriend and now she doesn't trust me at all. I haven't lied to her about nothing since then. But she is still always accusing me of lying and doing stuff I'm not doing. The reason I lied in the first place was to protect her feelings... and I would have told her the truth eventually, but she found out before I was ready to tell her. I can't go anywhere without her saying I'm lying about where I went. She says I have to prove I'm being honest. I thought never lying again would prove that but apparenly that's not good enough for her because she don't believe me. What can I do to prove to her I'm honest

You can't 'prove' you are being honest. And telling the world and her that you haven't lied since - how do we know that's true or not? You have a tough assignment and just have to accept it, be as caring and responsible as you can be, and if after some weeks or months she still isn't forgiving you, consider it a lost cause and leave. You don't say what the lie was. Saying that you lied 'to protect her feelings' is totally bogus in most situations, and if you had used that excuse with me I'd be long gone. A one day fling that will not happen again, so you think it doesn't count? Bogus. Finding out something about a family member or friend of hers that might hurt, and you aren't sure if it's true or even any of your business, understandable.

You lied to her. It's normal for her to think that because you lied about this that you may be lying about other things. You are the one that has to regain her trust.

You can't just tell her that you're telling the truth and have her believe you, you have to show her. As they always say - "actions speak louder than words". As time passes and she sees that your actions are sincere, then she'll get her trust back.

That's why people say a relationship has to be based on trust, if you don't trust your partner, there's no reason to keep dating. You should tell her that you lied to her to protect your feelings because she's always very protective about you and you'r afraid of telling her stuff and she gets angry. But I mean it, not trusting is the worst thing for a relationship. You should really expose your feelings to her.

As you can see the damage has been done, and she has not gotten over it, and may not forget about it entirely. Understandable since it must have hurt badly.

But if she has forgiven you, she doesn't get to throw it in your face at every chance. You made a big mistake, true, and have learned, and are trying, and if she can't let it go, then you have little choice but to let her go.

Holding on to those feelings, is not working on regaining trust. And does neither of you any good. Sorry.
