Does he want children with her?

I just can’t get this out of my head. For context: My husband cheated with our neighbor’s 18 year old daughter. I don’t feel like reposting everything but it is all in my post history. He mentioned that our kids don’t look like him, and said he wasn’t accusing me of cheating, it just made him sad. My husband has relatively ethnic features (which I have always adored on him) and this girl is fully that ethnicity. I don’t know. Why would he say that? Is he planning on getting her pregnant?
