Is this a valid reason?

Little back story - I came from a 6 year, toxic relationship. He broke it off because he wanted to go public with the woman he cheated on me with. Obviously had a lot of issues after that.

I took the time for myself and for once was happy about who I was. Eventually this guy came along and we hit it off right away. He wanted me around all the time and was nothing but kind to me. He initiated PDA quite often and I wasn't used to that. I saw no red flags whatsoever. He eventually asked me to move in, but I still kept my clothes in a bag. We were able to communicate about everything and I was just feeling like I could fully trust him. He asked me multiple times to hang my clothes up in the closet.

We had the "kid" talk on our first date and everything seemed fine. Out of the absolute blue he approaches me after dinner and tells me that he's been thinking about it, he knows I want kids but he 100% doesn't. Here's the thing! I can't have children. I brought that up but it didn't matter to him, he said he "didn't want to hold me back".

Sorry for the longer post I just can't wrap my head around that being the actual reason and why we couldn't sit down and talk about it first.
