You have to decide how long to give this other person power over your thoughts. Is it worth the energy you are currently expending worrying about it? If you don’t see that the you two can remake your bond - and you did say you are not sure you could trust again - then what do you hope to accomplish? At any meeting - civil or not- You will go away thinking you were right, while they go away thinking they were. This doesn’t mean you have to become enemies - just former friends. Be at peace.
