I don’t know what to say

My ex fiancé told me that he’s very sad and jealous of his cousins because they recently welcomed 2 baby boys to the family. He said that could of been us right now. He has been ignoring my daughters video chats since yesterday and his excuse is i love her but I just really wanted another baby this year and we couldn’t because you didn’t wanted to and im sad atm

Note- i asked for another baby and he said no im not ready maybe next year. I broke up with him about 3 months ago because of his mistakes

I don’t know what to say or how to reply
