<human>: My SO (21f) and I (23m) have been going out for about 6 months. When I left town for a few weeks I gave her a spare key to check on the place. I am glad she has it in case of emergencies or other unforeseen circumstances.  She sleeps over often and leaves some of her stuff over (which is fine with me) and may need to get to it if I'm not around. However, I don't want her to feel like it is her place. I told her to tell me if she is on her way but she reacted unfavorably when I said this.

I don't think it is unreasonable for her to tell me she's coming as opposed to just showing up and opening the locked door. I care for her very much and have nothing to hide from her. I just think its weird for her to be showing up unannounced when we have only been dating for six months. However, she thinks its weird that I asked and feels like I'm hiding something. Apparently, none of her previous boyfriends felt this way. I told her that its important for us to have our boundaries. Am I being unreasonable?

Provide a brief overview of the text.
<bot>: GF has a spare key; didn't react well when I told her to give me a heads up when she's on her way.
