I don't think you're rushing him !

I don't think you've taken into account her behaviour during the whole of their relationship.

She may not be unreasonable now (although they've only been married for 8 months!), but I'm guessing her baby craziness has really scorched the earth during the entire or the relationship.

Everything about this relationship screams intense and fast, with a lot of pressure on the guy.

We made plans (signed a lease) to move in together less than a year

And

would talk about marriage pretty openly all the time

I have to wonder if it was a 'we' thing or just her bringing it up all the time.

casually mentioned starting to think about trying for a baby in about a year

That's not something you casually mention. That's something you plan together with both people in agreeance. It's no wonder he freaked out.

It's clear OP had every step of the relationship planned to get to baby-making whether her husband liked it or not. Even when he told her he wanted to be married first, she imposed her timeless without a single regard for when he wanted to be married and how long he may enjoy being baby-free as a new man and wife.

Honestly, it sounds like he was gung-ho at the beginning and has had that joy stripped down by her intensity and obsession. She has tried to impose baby timelines less than a year into the relationship!!

And at the time, she would have been 27, not 37. So the excuse for expiring ovaries weakens.

OP needs to take some of the responsibility for the role she played and is playing here. She may have felt she was just being open and honest, but it sounds to me that she has put immense pressure on her husband. And with the daily crying because once again her (not their) timeline has been broken, she is being a bit manipulative (whether she realizes it or not).
