Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

 

The Nafaqa is the husband’s responsibility to care for the family and household. No man should ask to break marriage because of such reason. Maybe there are other reasons you need to see what they are with him. I suggest that your dad contact him officially with a local Imam and see if he wants to continue in this marriage or not. And based on his answer, you proceed for what is the best for both for you.

 

Almighty Allah knows best.
