I moved in with my aunt and uncle a few months ago on a short-term basis. They are an amazing and kind-hearted couple. They took me in after I split from my baby's father. Their home is luxurious; swimming pool, spa, fully equipped gym, library, cinema, stables. You get the picture? I invited a friend to visit me for a few days. We have been friends for approx. 8 years but not actually met up for the past 2 years. I felt thrilled to be able to meet her again but I want to end our friendship now that she has visited. Why? Because she has ignored me the whole time and I can't wait for her to leave. I thought we would spend some time doing things together and some time each doing our own thing however she spends her days using the facilities and taking selfies. She chats to my aunt and uncle, mainly discussing what she can use next, and doesn't include me in her conversations. She cooks her meals whenever she wants to and then refuses to join us for dinner because she is "full". I told her that it would be nice if she postponed her evening meal so that we could all eat together but she ignored this.
I invited her here to spend time with me (I didn't tell her about the facilities) but now I feel used and that she has embarrassed me in front of my aunt and uncle. I jokingly said that her selfies show her spending time using the facilities but none show her spending time with me. Her reply was, "It is MY holiday".
I will soon be moving into my new home and she has said that she will be "round there all the time". She already knows my new address but I don't want her there. I want to end the friendship when she goes home in a few days' time. AIBU to feel like this? Also, what is an effective way to end this friendship and what should I say to my aunt and uncle re: her embarrassing behaviour? Please help.
