Does this mean he was with another woman, and what should I do?

A guy I'm seeing was supposed to spend new year with me. He cancelled last minute. The day before he cancelled he went AWOL. Phone was switched off.

When I saw him yesterday he just made a random excuse up. I asked if he was with another woman. He didn't deny it or admit it. He changed the subject. When I pressed him to answer he went all huffy, like a child, on me. He's giving me the silent treatment now. He also made out us meeting up over new year wasn't a big deal

What should I do? I don't trust him now. I feel hurt that meeting up at new year means nothing to him. Seeing him meant everything to me 😕
