Searching for people

How would you feel finding women in your husbands search history on Facebook? I don’t usually snoop because I don’t feel the need to but we have had an ongoing problem in our relationship of my husband searching for random women on Facebook. So sometimes I get curious in hopes that he isn’t. Some from his place of employment others from our hometowns or just random. It has ALWAYS bothered me but I can never get him to tell me why he does it. This time around I felt different about it not mad, but hurt really. I told him it’s him lusting after other women and I don’t like it. It’s one thing if a pretty woman walks by like hey I get it or even if they pop up on fb and you do some snooping but to go looking for it is different to me. We’ve been talking about having kids and our next plans but I just feel like maybe we should wait. We’ve been together 9 years and 1 married. Idk just feeling a little sad and needed to vent.
