Need some advice?

So I said something that really pissed off my partner... Now partner won't respond to me to talk about it. I messaged partner to apologise because what was said was taken the wrong way... Partner stopped responding unless I ask a direct question About errands or my health... And they are short. And unfeeling... Otherwise partner does not respond.

What is this behaviour? Is my partner finished with me? I don't know what to do... I'm so stressed I can't eat or sleep.
