Search History

So awhile ago, I was in my husbands Fb & looked at his search history & noticed that he was searching this girl that he use to be super into & almost basically left me for before we were even engaged. Anyways it showed him searching her several times a week, multiple times a day. What concerned me was that he was searching her name & pulling up her private Fb page (he's not friends with her on Fb) where you can only see profile pics & cover photos, at around the same time every day 5:30am when he got home from work. It sounds very odd to me. Like why!? I asked my husband & he said he was probably just checking out her page & then he said ,it must be a glitch & that he wasn't looking her up several times a day.
