Does a Muslim Pakistani man still need to seek permission from my non-Muslim family, including my father, if I, a revert lady, am interested in marrying him?
Bismihi ta'ala
Yes, whether the female is Muslim born or converted to Islam, he will still need to follow the correct shar'i and traditional Islamic custom of process of proposal and everything else. Involving family in the marriage proposal is extremely important, and so is seeking their blessings and happiness.
And Allah knows best
