Sure wish I had solid answers for this question....all I have are thoughts. Trust is achieved in baby steps. You don't give the keys to your house to a total stranger, but you do give your keys to a trusted friend. It takes time to develope meaningful relationships. You first trust a little, and when that is not violated, you trust a little more. Baby steps. Hope this helps...best wishes.

Trust is not an all or nothing issue. You can start out by trusting people a small amount and build on it. Remember trust is not about you. Base your trust on the actions and the character of others.

Whenever someone gives you reason to not trust them anymore, let them know. And then begin making decisions based on that behaviour.

For example, if you notice that someone acts out of anger, well, they may get angry with you one day. When someone becomes angry and volatile under the influence of alcohol or drugs, remember it may be directed your way one day.

When people act with consideration and kindness, remember them. It isn't a foolproof method, but base your trust on your observations.

You cannot control what others say and do, but you can limit the impact that they have in your life.
