<human>: Am I being unreasonable? We spend almost every hour together, during the day we're together mostly and in the evenings it's automatically assumed either that I am staying at hers or she is staying at mine unless otherwise previously stated. 

It's reaching finals week and things are getting stressful. I've just had one night off, I stayed at mine because I had to get up early while prior to yesterday night, we've been at eachothers everyday since Thursday. Even with last night to myself, I still didn't feel like it was truly just to myself as I wasn't feeling good. Am I a dick for asking for space or for time to myself? 

Earlier, we had an argument on the basis that as I asked if it was okay for me to stay, she says its fine, but later says that her releative has fallen very ill. It's almost as if she had mentioned it purely to manipulate me into coming to hers? I just don't know what to do. I cannot win either way.
