If this is your memory of your first relationship, you may hope that therapy would help you find the strength to trust again in other people.
But deep down in the subconscious realm, there was a question being asked of the social part of the mind. “Why? This is hurting us. Why won’t you leave?”
Hypnotherapy is the most direct way of healing your trust in yourself. You’ll be amazed at the effect of saying “You were right. I’m sorry. This is what we learned, and it won’t happen again.”
