Do you think him breaking up with me about kids is true?

The first days speaking over the phone he liked me and the second day he said he liked how I think and was fine with me not wanting kids and he told me to call him the 3rd day early to know his final decision, but I was out for groceries and forgot my phone at home, so when I came home late he texted me that he wasn't interested at all... I understand he wanted kids but do you think me not calling him early made him feel off or something? Or just wasn't attracted to me at all?
