Ok ladies... I need some advice here

so me and my husband have been TTC for 3 months, married almost 4 months, together for almost 6 years. I completely trust him and would never think of him as the type to cheat on me. he is a genuine loyal man. but today he handed me his phone to add something to sell on FB and I saw a list of previously searched... names of 2 of his ex's and other women I'm assuming he knows from school or something. I did not freak out on him or anything I just asked why? And no responce.... Just wondering how any of you would handle something like this or if its even worth makeing a deal out of this?
