It is not your job to make him into a rabbi or something else.
It is your job to find a life partner who will share your goals and values. He is nm his own person too. You want someone who wants what you want to begin with. Imho. It doesn’t guarantee anything but you start with a foundation.
Btw I am also in shidduchim and have been learning this along the way. I was in a very unpleasant situation where I was going to change for the guy and it was too much pressure and it felt like drowning. Imho give that guy a chance to find his beshert. Give yourself the gift of finding yours.
