Having a Guy roomate signals?!?

Okayy I recently moved in with him. We haven't seen eachother in years and finally united again. The first two nights were crazy like wine and cuddling I slept upstairs the first night and then the second night he invited me down to his room we drank wine made out and it felt romantic so romantic woke up this morning talked for hours laying there. But today he had plans was.gone all day and when he got back he just kinda acted like I was a little buddy friend thing. Idk it was awkward... idk what he feels. Or what I should do
