I didn't know we can ask in English. I have been with a man for 6 years. We are distant family members but our families do not like each other much. My mother is extremely against it. She is not approving at all and has a list of reasons. I doubt these reasons can change, they are fixed ideas and facts that she does not want to change. I had some doubts about our marriage too but I got scared when she mentioned them because she made them sound like real deal-breakers. He is trying so hard to keep this going. He fought for me and is still willing to do so. I told him let's be realistic and accept the fact that my parents will not approve. He is very hopeful and optimistic and thinks he can convince them. I told him that they are not reasons she can change, and I obviously did not tell him all of the reasons she mentioned. I know what my mother means and I will be lying if I say I did not think about these reasons too. So, the logical thing to do is to leave him. But my heart cannot get me to do it. I love him way too much. So, is this just the normal pain of a breakup because of the attachment or is my heartache a sign that I cannot leave him? I am very hesitant. I prayed istikhara many times and all the signs are negative. Please advise, I am going to go crazy.
