Statement that does not constitute divorce

Me and my husband were talking and he asked me to give him milk, so I was like plain or hot, but he wanted a smoothy like milk. I didn't feel like making it so he was upset. I told him to have good character and show akhlaaq. He said that I do a lot of sabr. So I said, like my step mum? He said yes. (My step mum has a problem with her step mum in law and she dont want to keep her anymore because of issues they have so she said she cant make sabr anymore and she dont want her in her house). Does that consitute a divorce? Because he said he did a lot of sabr.
