I’m..torn...depressed... etc.

I finally ended up blocking the guy I’ve been talking to... let me explain... I’m 21 & I want 3 kids in my future (everyone thinks I want it right now and I try to explain that I don’t, just before I’m 30) and I want to get married. I’m very upfront about this, I tell guys that i talk to before feelings get involved, so if they don’t want any, they don’t need to waste their time and my time. I told this guy I’ve been talking to he told me that he doesn’t want any kids right now, then it changed to he doesn’t want any at all, my feelings were already growing for him... it was already way up there, I was pretty much falling for him already. His reasoning behind it was him having 3 kids himself and he’s scared if he has anymore he’s gonna get screwed like he did with his kids now... I told him I can’t be just friends with him because of my feelings for him... I told him this plenty of times, thought it got into his head. This was going on for a couple weeks.. of him and I going back and forth about this whole kid thing. I told him I won’t settle for less, and I’ll get 3 kids rather it’s with him or not. He told me that I might as well move out of state because guys around here doesn’t want 3 kids. 😂😂😂. But... after all of this, he continued to try to talk to me... I’m confused.. why would he continue something he knows won’t work out & knowing I don’t want to be friends with him?... i had to tell him to stop, and block him for him on everything to quit talking to me... It hurts a lot.... I don’t know what to do 😔
