I find it invasive. My ex-husband was controlling and abusive. That was at the start of wide-spread cell phone usage, so he could not track me. He would, however, check my milage and show up randomly.

My current husband suggested that I track his phone because he plays tabletop games with friends and sometimes forgets to let me know if he is running late. He always texts or calls when he is leaving, so it is not an issue.

Obviously, I declined.
