I told my boyfriend I loved him and HE SAID NOTHING?

So we are having sex and my bad on my behalf but I said I loved him while he was thrusting so hard cause it felt good af. And he said nothing and I know his ass heard me. We are still new been together almost a month. He tells me he cares for me a whole bunch but why didn't he say he loves me too?
