He ghost me for 3 weeks then all. of sudde text?

This guy ignored my calls and texts for 3 weeks and all sudden texted and said good morning GEORGOUS with a wink eye and kiss emoji. When I was calling he didn't answer or call back or text when I called from a different number a wk ago he pick up I ask why he was ignoring me he replied been working I said but u pick up and called this unknown #. Then I hung up because I was disappointed and mad. Should u reply after 3 weeks u think he call instead of text or should I not immediately reply or reply at all
