Husband looking up women on facebook

Would you be upset if you saw your husband look up women on Facebook after seeing their profiles on LinkedIn? My husband didn’t know I was behind him as I was walking over to the couch and I noticed him looking at a woman’s linked in profile, then went to her Facebook and looked through her profile pictures, then went back to her linked in. She is a young pretty girl that is his age, and turns out she just started at the company he works for, but this is his last week there. I thought this was kind of weird and it made me feel bad.
