What is a soul tie? Do you mean that you tolerated the abuse for such a long time that you got familiar with it as a way of life. Now you are grieving over the loss of what you never had? You grieve that you lost "what could have been" or "what should have been" but you are grieving over the loss of a fantasy?
Stop grieving over the loss of a never realized dream. Be happy that you have been delivered from an abusive relationship. It is not a soul tie you need deliverance from it is a new reality that you need. Or rather that of "facing reality"
It was bad. It wasn't good. You are not losing anything. When you start to imagine what could have been, remind yourself that this is not real. It is an imagination. Don't make the same mistake and build a new relationship on what "could be" and live in a make believe world in your head that does not exist in real life. Instead find someone who actually demonstrates the godly characteristics in the right now without making excuses for how they will do better in the future.
The desire to forgive others of their faults and believe the best for them and their future change that will never happen is a trap.
Believe the best for their future change from afar. Not while being in a romantic relationship.
Don't accept excuses. Seek someone who is consistently civil and polite even when stressed. There are plenty of them out there but it takes some time to discover how they act. Dating is not the way to discover them.
