What does he really mean?

During an argument weeks ago he said " The spark is gone" and we need "time apart " .

Is dude cheating? Flirting with the idea of seeing someone else?

We still have sex. He still holds me at night.we still kiss. Still calls me baby . but those words he said three weeks ago will not allow me to be happy. Cant talk to him. He doesnt like talking ab problems. Its just who he is..not trying to change him. But i troed to put myself in his shoes. I said those words to someone before...and i was the one cheating. So idk.
