Why do people have trust issues? why is it so hard to have one conversation with someone you don't know? is it because it hurts to much? or is it the fact that they are scared?

answer

When everyday stresses intrude into our protected space or an unexpected relationship problem disturbs our calm, we may begin to feel insecure and self-doubting. We may also begin to doubt our partner’s love, loyalty, and trustworthiness.  Without realizing it, we may react to these doubts by pulling away from our loved one in subtle ways.

Once someone is let down once, they usually grow more scared of letting people in because they are scared of being let down again, and they grow trust issues. It is hard to communicate with someone with trust issues, but all you need to do is stay a true friend and listen to them as much as possible. You can help them by showing that you are going to stay by their side no matter what, and maybe they will open up.
