Why would my husband delete me as his background?

My husband is deployed and recently he was screen sharing with me and I noticed that I was gone from his background, our wedding picture was replaced with some generic plain background. I asked him about it and he said he did it when we had a fight. Im deeply hurt. I wouldn't just erase him like that. Am I being over dramatic or is this a red flag?
