He needs to grow up.
I too used to burden my loved one with hulking expectations beyond her abilities in years past. I was inexperienced and very egomaniacal in that regard. I wanted to shape her completely the way I am, thinking that by doing that we will love each other more.
What happened is that she started comparing herself with other brainy women I frequent, and judging herself. "I wish I was as smart as the other women so that I too can talk to you about the subjects you're passionate about", "I feel like I don't deserve you", "I'm trying, but I feel like shit because I'll never be as sharp as X, or as charming as Y".
She fucking judged herself harshly out of sheer love, just because I once said "I wish you could see the things the way I see them".
That's called fusional love, in which a partner seeks further security and understanding by seeking a chimerical concept of Onness.
Here's the kicker. Her and I, are actually both complete by ourselves. An ideal relationship is to complement each other, not to complete each other. The latter opens up an eye-opening experience in which we appreciate the other person with all their differences and idiosyncracies, in which both the parties are free to be.
I like driving fast cars while listening to a Soren Kierkegaard's audiobook read by Lady Lazarus, while you like watching Korean Drama while eating the whole caramel collection of Häagen-Dazs? Big deal. It doesn't matter what weird shit you're into as long as I chose you. If it's some odd pedo-coprophilia crap, however, I'll simply break up with you and move on instead of judging you to make you feel even shittier than you are.
If your love interest is smart, he will realize that soon enough. If he can't, spare yourself the anathema and tell him that you can't force yourself to change into something you're not, and just move on.
