I want to change my daughter's last name to mine. I am pregnant again with the same guy but we are no longer together. My ex hasn't asked about the baby once and has ignored anything I tell him about the baby. When I told him I was pregnant he said he didn't want kids and left me shortly after. I gave my daughter his last name because we were together and talking about marriage. Now there is no hope for us. Can i change her last name without his consent? I want more kids one day if I find a man worth keeping. I don't want my kids to have different names.
