Help someone with a possible stalker(s)?

This is confusing to explain as someone with no experience in website analytics but I hope someone else can make sense of this.
I have 2 tumblrs, both set up with statcounter. I also have someone in my life who has admitted in the past to checking up on these blogs frequently. When I first installed statcounter, I noticed someone in the area he lives/works (tristate area) with his particular phone and laptop checking my blogs a lot. Let’s call him A. For what it’s worth, on certain days of the week, A randomly pops up as an IP address in a different state. Sometimes randomly in different states, but it still shows as the label A (using the label function on statcounter) and his phone/laptop model.
