He makes me prove everything

Yesterday my fiancé FaceTimed me so that I could show him what I was going to make him for dinner, like what I bought with the money he gave me. I did and he just stared at me. I asked him what was wrong and he asked where I was.

I was literally at our house.

He said there were popcorn ceilings behind my head and we don’t have those. I was confused and said those were our ceilings and he said “show me then” and I did. He said I was being smart with him and he didn’t want to get into a fight about something when he’s already dealing with a lot at work. I was confused and he hung up on me.

He did the same thing last week when he said there were two phones in a Snapchat I sent him of me and my dog (yes we use Snapchat still but only occasionally). There wasn’t and it was just the mirror behind me making it look like that. He didn’t believe me and made me prove it. He said it looked like I had a secret phone or something. Once again, I was confused.

What am I doing wrong? I need advice, I don’t get it.

Edit: I posted a comment but I wasn’t sure if anyone saw it. We’re safe now, thank you everyone for the advice and the love ❤️
