Why are you no longer interested in him?
You can't choose. In this case, a “teacher” will come to you, and not a partner who will drive around the patient. Such men do not appreciate, do not hear, change.
You don't value yourself. This leads to constant dissatisfaction on your part and depreciation on his part. If you don't value yourself, how can a man appreciate you?
You don't know how to build trust. Conversation on difficult / painful topics quickly develops into hysteria, tears, interrogation or edification. What is important to you, you are trying to get through blackmail, resentment, manipulation. As a result, mental coldness develops into physical. He doesn't want you anymore.
You don't know how to keep your dignity. You don’t know how to stop attacks, criticism against you with dignity, set boundaries, put him in his place so that he realizes and apologizes.
