ANSWER:
You are allowed to see your potential spouse before marriage at the initial marriage interview conducted by your father.
If you were not attracted to him, there is no problem in refusing as you are the one who has to live with his looks for the rest of your life however, you must not be too picky as the supply is more than the demand and so many women end up NOT getting married due to being too picky. You don’t need to feel attracted to him but rather you shouldn’t feel repelled or annoyed by him.
