I think that if you need to have "faith' in a program, you are already headed toward failure, because nothing is perfect.
In your post, you talk about "faith" and what other people have done and your relationships to them. You talk about your past.
What you do not talk about is what you yourself have done for your recovery.
Whether you stay in AA or leave, the focus needs to be on your action. A sponsor does not recover you. A program does not recover you. You recover yourself.
Dumping the first sponsor sounds like a good step. You have come to a recognition of some of your own psychological issues. So now---what do you do with that? There are a lot of good reasons to leave AA. I left myself. But leaving because you had a screwed up sponsor? That is life. There are many people who will hurt and disappoint you.
Will you always walk away--or drink--when someone you care about does this?
Choose you next action carefully!
