Guys, Asked my friends with benefits if he was free tonight and he asked me how my day was?

So texted my friends with benefits yesterday if he was free tomorrow night and instead of answering my q he told me that he’d just got back from work and asked how my day was. We had a short conversation about how our weekends went and he said nothing about being free or not.
It’s left me very confused

Should I ask again?
