Thank you for this brave post, speaking on behalf of so many.
Those who have been hurt were given a gift from the one who broke their heart. They are now stronger, tougher and more connected with their intuitive self. Indeed, they have built walls. Indeed, they (think) they have trust issues. But all is well, as they are in the process of allowing their divinity in.
There is no point in processing, thinking "how can I trust again, how can I get over my doubts, how can I fill myself instead of feeding off?". All these questions are food for the mind but they mean nothing for the process, and they don't influence the enlightenment.
Those people who have been hurt will feel one day that they are ready to start over, love again, trust completely and with no fear at all. How come?

They will know that it doesn't matter. That they can be betrayed again, bitten (emotionally) again, left alone again, but they will always always have themselves. And the discovery of this wisdom will free them for eternity. And they will love and be loved like never before.

This I promise you.
