been talking to this guy on a social media site?

Timothy and Jaco have given some good advice. I'd like to add to that.

Until you can learn to trust other people, regardless of what happened in your family, you will never have a successful relationship. Please find someone you can talk to, at church, school, or a valued relative or older friend (for instance, a friend of your parents in whom you can confide). You have to overcome this for everything you want in life, including a job, business transactions (when you're older and want to buy a car or house, for instance).

Healing can happen, but it sounds as though you need to face whatever hurt you and work through it.

As for meeting a boy who you "100% trust" that he's who he says he is, hmmm. I would not only meet him in public, but I would take someone with me. A friend, perhaps. If he's unwilling to meet you in public without a chaperone (aka, friend or parent), then he's not the kind of guy you want anyway. And with the number of fakers online, and stalkers, I would not go anywhere in his vehicle or with him alone until he's been "man" enough to meet your parents.

I wish you the best, and gentle healing.
