Imagine your mother told you that you are not her child. She found you somewhere and brought you home. Raise your child to give you care and love like a parent. Then they told you have to leave. How do you feel? It will hurt you, right? you will feel that you have lost your life once again there will be no reason to live. You will collapse and burst out inside. But you can’t even express to anyone what you are going through!!!!. Imagine the scenario
Your haram companion taking your responsibility giving you love and care. Feel you special. Spend quality time with you. After that, he told you it's not working out.
He lost interest in you what will happen to you? you will try to stop the person. But you can't.
One reason because the person takes responsibility without any authority. There is no deal no Contract no evidence. Your authority is unknown about your circumstances and also the person's authority.
So the person can leave you at any time any moment. There can be also a reason the person's authority is not accepting you. So it will come to an end for sure. Any relationship needs authority but this type of relationship has no authority so how it will work? so the responsibility without authority is meaningless and it will break you one day.
