Why did he lovebomb me then suddenly breadcrumb me?

He was calling everyday, sending meaningful texts, bringing up future dates. He complained that I was texting too slow. Out of the blue he stopped doing all that and only texts "Wyd." He brings up coming over to my place, no longer talks about real dates. Did he lose interest or was he always not interested?
