Why not? If we love each other immensely and both want children,

Cause you're still in the early 20s, still growing up yourself, and you've barely been dating each other for that long. The whole honeymoon period lasts around 2 years....

I don’t think our honeymoon phase will ever end honestly, that’s what happens when you really love somebody.

There's clear biological differences in hormones etc. in the early stage when a couple gets together, and once they're together for some time. Yes, you can keep the spark alive, but the honeymoon period always ends at a certain point.

. We both want a larger family, and I don’t want to have kids after 30, so here we are lol.

Yeah, and at the same time you have huge issues with your SO, he can't communicate properly with you, you're hurting.

Again, time for counseling.
