in 5x21, Rumple approached Moe, and Moe told rumple to go to the UW. (Ok, maybe he didn't say exactly that, but the sentiment was there).

Ok, seriously, when Rumple approached Moe about waking Belle, Moe told Rumple that Belle was better off in a sleeping curse than being awake and with Rumple, and that so long as Rumple existed, he was not going to wake his daughter. When rumple threatened Moe with the Cane of Pain, Moe responded that he'd rather die that wake Belle to be with Rumple.

That is where Rumple comes up with saying Moe refused to wake Belle.
