Salam alaikum

I do not believe that there are any Wazifa as you called it that will make people love each other. Love is a feeling of attraction towards something seen as perfect or needed. Marriage comes in levels: the minimum has to do with liability in financial support and no abuse. Many marriages are surviving on that but of course it is not what Islam teaches that spouses should stop there. The maximum will include tranquility, love and mercy as Allah the Almighty described in the Qur’an.

My advice to you is that when he comes back to have a real talk with him as to what he plans for this relationship. If you are giving it all effort to make it work, ask him if he is willing to do the same. He must be clear of his intentions and step up to his manhood and take responsibility. If he needed just help as to guidance, seek local imam counseling but if he said he is not interested anymore in this relationship or marriage, start thinking really of the worst scenario God forbid and your plan for that.
