My son since he got engaged has stopped loving his parents. He talks to us when in need of anything may it be money or advice. He is inclined towards his in laws and fiancee.
What duas can I recite to get love and respect from our son ?

You can revive this relationship with your son with lots of love and positive communication with your son. Its important you keep the communications channels open and pray for them. Please turn back to Duas from Ahlulbayt a.s. Hadithul Kisa will help you
