For a lot of people, it's not about "Why should I trust you?", it's about "Why should I distrust you?"
This is a big barrier in why your relationships with people in certain demographics are so shallow.
You are too busy trying to prove to people you're safe as a person.
You should be deconstructing why you are unsafe for some people and working on fixing that.
If you are unsafe to be around, people will not trust you and those who do will be hurt by you.
