Is this being jealous?

I ve been on a few dates with him.
He asked me where I was going and I told him to get earphones
I met a male friend and he saw us walking together.

After that, he became cold and distant towards me. He wouldn't say hello, gave very forced smiles and wouldn't talk to me on his own until it became awkward as I was standing there and he wasn't saying anything.

Was he jealous?
He is a distrusting guy and does have trust issues
