I wish I knew the answer to this because I’ve just been through 2 weeks with a horrible house guest. A childhood friend turned out to be someone different from what I expected. She complained constantly. Nothing made her happy and she lived a completely different lifestyle than us. She was a hypochondriac telling in detail every ache and pain, ever condition and what pill she took for it, all the while grinning like it waas a great thing. She questioned everything we did, how we dressed, how we ate and when, how we talked and she didn’t want to do anything but sit and play games on my IPad which happened to be logged into my facebook. She started making comments on my group chat with my daughters so reading my private messages. She hardly showered at all because she doesn’t go outside so doesn’t sweat. It was disgusting. Suffice it to say it was a really long 2 weeks and we were stuck because she had no family here and bought a round trip airline ticket. When things went too faro over the top I would tell her so but every thing that came out of her mouth was negative and I couldn’t keep up with every thing she did or said that was inappropriate. I feel like I have PTSD and would love to learn how I could have handled it differently

UPDATE: It’s been a whole year since I posted this and I’ve spent that year analyzing what happened. I learned so much while examining it all and I’m convinced that this person is a narcissist. I know now that I will never find myself in this situation because I have learned how to make boundaries which I didn’t do back when this happened. No one will ever invite themselves to my home for 2 weeks. No one will be permitted to rule over my home the way I allowed this. So much of what happened during those days, I could have put a stop to if I had understood my rights to set those boundaries. I’m grateful now, that it happened because I have grown and learned. It’s all good.
