Is he not interested anymore or jealous?

We were fine until I was going out and didn’t answer his phone call so his last text was “have fun” previously that day he asked for my last relationship and ignored me when I was talking about my ex when he literally was the one to ask and now he’s ghosting me 🥹 I won’t humiliate myself but why though? He’s just sending me funny reels on Instagram but no talk like before. He switch immediately after that day.
