<human>: 19F here. I've been dating my boyfriend (20) for almost three years now. Lately if he tells me he has to go somewhere, I'll ask him where, he'll say "it's none of your business". Or just in general, he'll tell me he has to do something, and when I ask about it, he'll tell me it's none of my business. This bugs me a little, but am I wrong for being bothered? I don't understand why he'd tell me he has to do something and then tell me to mind my own business when I ask about it. Nothing too big, not much of a deal breaker, just wanted to know if I'm wrong or over-exaggerating for being bothered by it.

Summarize the given text in a few sentences.
<bot>: Boyfriend tells me to mind my own business after he tells me he has to do something and I ask about it. Am I wrong for being bothered by this?
