<human>: Could you distill the essence of the text into 1-3 sentences?

My girlfriend and I have been going out for nearly two years now, things have been going great and we haven't had any major issues. We both trust and love each other very much. However the other day she admitted to me that she has been logging onto my Facebook account privately and reading through my messages over the past week or so. Now I've got no problem with showing her my messages and have absolutely nothing to hide, but I think it's important that we both have our individual privacy and her doing this feels like my privacy has been completely exploited. Because she knows I'd gladly show her my messages she thought I wouldn't see a problem with her doing so, but once I told her how I felt about it she understood why I was annoyed with her.

She says she was not snooping on there in a bid to find me flirting online with other girls or anything, but was just curious as to who I talk to etc. She said she was sorry and would never do it again, but I still can't help but feel strange about the whole situation.
