How do single mothers date?

I just dated this guy for the past few months since my baby daddy & I ended things. He’s the first person I ever had around my twins. It ended because me having kids was too much for him basically “I want a family one day and you already have one”. Do you single moms date guys who don’t have kids? Or guys who have kids? My heart hurts and I’m mentally not ready to date or bring anyone around my beautiful daughters again. Just want to know for next time.
