After being discarded for the second time, should I expect a narcissist to return again?

We have been together for 3 years. He broke up with me once, last October. In December he wanted me back and I reconciled with him. Since then, it was mostly peaceful, no major issues. 2 weeks ago, all of a sudden he picked a ridiculous argument, told me to go home and hasn’t contacted me since. I texted him once, he left me on delivered so I deleted it after a few hours.
