Boyfriend doesn’t trust me?

Ok so I went on a walk around the neighborhood by myself at 8:00pm. I asked him if he wanted to do something but he wanted to play video games, so I went on a walk by myself.

And I guess he didn’t know I went on a walk so when I came back home it was almost 9:00pm and he doesn’t believe me that I went on a walk around the neighborhood

Idk what to do? Like I can’t really prove that I went on a walk

He says i sound sus

Because his point of view I walked in the house at 9:00pm and thinks I sounded sus when I said I went outside and walked
