Possessive?

Hello,

Just trying to get some feedback if this language seems possessive.

The Dom and I talk big relationship issues the first of the month. We have been having some issues lately, mainly with communication. What he is referring to is when we meet at the first, I may tell him I don’t want to belong to him anymore. I told him I have been thinking about this. This is his response:

You are mine Nine days is just your opportunity to make that request. I am not releasing you. Period.
