I told my bf I’m “not sure now” about having babies with him

I told my bf I’m “not sure now” about having babies with him. <br><br>We’ve always said we wanted kids, so this was unexpected for him. He’s been asking me why and I’m not sure what to tell him. I saw a picture of him as a child. He looked very nerdy and had a big smile. He looks nothing like that now. The picture of him as a child was surprisingly the first picture I’ve actually seen of him as a child with his parents. In the photo, it was his mother and father and two sisters. He didn’t look anything like his father. So I started to wonder about his paternity. From there I started to realize what his face and body would actually look like if we had children together. I’m really not sure anymore. I’m just not ready to bring him back to his childhood. He’s called me twice today to check in and hasn’t texted me at all. He’s not okay.
