He wanted children and I didn't? We we're together for 2 years and he knew from the start that I didn't want kids?

he decided to break up with me cause he said he wanted to be a father a d I didn't want to be a mother, in the beginning I made it clear that I didn't want kids but he committed to me anyways and I truly thought he loved me and wanted to be with me for the rest our lives. But now he has left me for a younger woman who is 26 something, he is 41 and I'm 31..

What should I do In this situation? My family isn't happy with me cause of my decision of not wanting kids and the fact my partner dump me for it, my family says that its failure for me...

I feel like just wanted to pass time and wasn't serious about me...
