My boyfriend recording another woman?

My boyfriend recently went on a trip and sent me some videos. One of the videos was of him recording a girl. He was clearly attracted to her and I could see that she was looking straight at him while he was recording. He knows I’m very sensitive to something of this nature as my ex-husband used to cheat on me. He doesn’t seem to care that this would upset me. Is this a red flag?
