Suddenly he ends things because he is moving away?

I met this guy once and there was an overwhelming spark on each side.

I Then went on vacation and he wrote me everyday, asking when I'll be back

The day of my flight, late night he wrote me saying he hopes I had a good flight. Next day I texted him good morning but he didn't reply which confused me a lot

now after three days, he apologizes saying he had to sort his mind and he decided to accept the job offer abroad which had been on the table for a long time

He wished me all luck in life and said he therefore no longer wants contact

What should I say? Should I even respond? I'm very heartbroken he chose to meet me although he was sure leaving the country behind, not paying attention to my feelings

Suddenly he ends things because he is moving away?
