Too many questions here:
Is he interested in that way?
What’s his current involvement in learning?
What is his overall hashkafa in terms of lifestyle he wants to live (minyan, schools he would want to send his kids to, how he would want to raise them, etc.)?
These things can seem less crucial when you are just dating, but once married they can make a world of difference, if important to you. You have to trust and respect him religiously.
I think you need to ask more questions before seriously considering if he has potential or not.
