Need advice for a close friend.

She went to search for something on Google. The previous search phrases appeared when she started typing.

The short; his gmail account was logged in on her phone. She has his password and he knows, as they have some joint accounts for things that are under his email. (This is on the safari iPhone app) Google apparently tracks what you search. So after seeing " (local area) Craigslist backpages" and "(local area) backpages", she got very upset. She doesn't usually use safari to google things, she has the Google search app and typically used that but was already on safari.

After finding that, she discovered that Google apparently tracks your search history and saves it to your email "user". It's not in the safari history, but rather a history tab when you are on Google in safari, and logged into a google account.

She found searches for escorts and escort reviews. A few searched phone numbers for reviews, as if looking for reviews on an escort based on a phone number.

They are long distance right now due to work, but moving shortly. They are engaged.

Of course, she didn't mean to snoop but dug a little further after seeing searches for escorts. It's happened 2-3x in the 6 months they have been apart.

I'm heartbroken for her. I don't know if he was looking for an outlet of porn.. Hoping to get more realistic photos...!? There isn't anything that proves or shows he met any escorts, but why the hell would there be searches!?

She doesn't know how to confront him and I don't know what to tell her!
