Gosh, this is a tricky one. I can understand why you'd feel uncomfortable - only because he used to share his location and then stopped, without a reason, and won't do it again.
It doesn't mean he's up to no good, but I can appreciate why it would make you raise an eyebrow and feel uneasy.
It's great that you're deep into self-awareness and are at least willing to look at what might be going on inside yourself to cause your reaction. And you're also open to the unpleasant possibilities that are crossing your mind. I hope it's just your overreaction.
A very well-written and insightful read ... difficult to share, I would imagine, and I'm sure you're not alone in your feelings.
