To me, this does not actually sound like a boarding agreement. Usually when couples break up, they immediately return all of each other's stuff. When pets are involved (including horses), I think it's typical to say "Yes, I will keep feeding your pet until you make arrangements to come get him." - with the assumption that you will be getting your fur-baby ASAP.
Certainly, he didn't say this was an indefinite arrangement?
