Standing here very confused

You need to know. Try this:

Forget your phone when you are out with H. At some point say "oops, I forgot my phone let use yours to call ______" If he hesitates, says no, or fumbles around with it first (to delete stuff) then you have your answer. If he gives it freely it doesn't mean it's all OK (since he may delete stuff regularly) but it is a good sign.

I think snooping is OK to find out what your dealing with. After you know is when you will have to determine to continue.
