A family member thinks I am lying about where I am going but I'm not, what should I do?

I know how you must have been feeling if the person whom you are connected to wouldn't trust you. You can do everything in your power to communicate better and maybe prove it to the said member and find out where if there ever was, any kind of communication gap. But, in the end, all you can do is try. You cannot expect them to trust you. You are gonna have to accept that. Make peace with it. Accept that the family member is not trusting you as of now. Try to earn their trust, and if the person still doesn't trust you, then you have done all you can. Good luck

Find out why they don't trust you and if needed let them take you to where you are going to prove to them you were telling the truth

first and foremost proceed with caution, and keep the importance of your safety at the forefront of the situation: make sure that at least one person who does believe you knows where you are going and what you are doing. secondly, if that person thinks you are lying there may not be much you can do to change that. if that person thinks that, then their trust has probably been betrayed enough in the past, that they have become cynical and disbelieving. you could try to show them through your actions that you are trustworthy, but I can't promise you that will work. not everyone can be convinced.

If you aren't lying, I wouldn't worry too much. It's up to them to believe you or not. You could always send your location from your phone, or take a picture of something that would prove you are not lying.

I would sit down and respectfully ask them why they are questioning me, and try to understand their point of view.

You could message them proof the next few times you go somewhere and you will gain their trust after a few times.

I've also dealt with this issue, stand your ground, you are your own individual; you know what's true from what is false, if needed, provide evidence. Some people, even someone within your bloodline, has a hard time trusting people.

Show him/her that you are a reliable person. Maybe trying to impress the family member by doing the dishes or something like that. It is probable that he/she thinks that you are not responsible and doesnt trust you.

Are they a close family member? Do they live with you? Support you? Take care of you? I don’t know your age but if you are a minor and this person does none of these things for you and you live with your guardian, the only person who should be questioning you is that guardian. If you are an adult and this person still does nothing for you, then they should mind their business. However, if you want to peacefully put this to rest, ask them to come along or text them a selfie at the place you are at and show them.

Have you considered just taking them with you one time? If you show them where you are going, perhaps they will stop accusing you of lying.
