Help me realize… I’m not losing out

I - 28 female - matched with 36 male on dating apps.

We talked for about a month. We clicked right away. The chemistry was strong. He told me he told his friends about me. We talked about our future. It seemed like I finally found my person...

He has kids. I do not. It was not my ideal scenario to date someone with kids... but I really liked him and wanted to try.

I did mention my hesistation about kids...and he pulled away completley. However, I did try and plead my case telling him I was scared initially but wanted to try after getting to know him.

Fast forward he totally stopped texting me as much. His energy was very different. I felt myself becoming very clingy and needy... because he was pulling away.

He said he liked me a lot but needed things to go slow... long story short... I asked him to give me more in the relationship he said he couldn't.

And im just so sad... I feel so rejected and like I ruined it. I tried to make up for the fact of me being hesitant about his kids... but it was too late.

Now he says im asking too much of him. Putting too much pressure on him. He can't give me what I need. All the lines in the book.

Edit: Thank you so much to everyone who commented. Yall definitely helped realize I deserve better.
