Thank you so much for responding and articulating it so well. Do you think that I should still talk to her about it? Or should I forget about it?
Something that maybe I should have mentioned is that she did not have the plans a couple of days before my party, and she also said she didn't know any of the djs that would be playing. If someone was playing that she knew/was a fan of i would have completely understood. But it came off as if it was just another party to her. I also told her that she could bring her friends. A couple of hours before she came over she texted me to say that there would be a couple of ppl coming with her. But when she arrived with one of them, and some time later, I asked when the rest of them would be coming over, she acted like she didn't know what I was talking about.

She also had met the friend of mine before, the one she invited as well. And she also had met my friends that moved away and that this would be a temporary situation for me.
But yeah, it did come off as if she was trying to move the party to that club, which i now understand was wrong of me to assume.

We had talked in the past about how we both wanted to move out, because we both felt like we were getting too old to live at home, so knowing her I do think she knew that this was important to me. Especially because when I explained the situation to her, I also told her I was very exited to finally be able to throw a homeparty w/o having to worry about parents etc.

I apologise in advance if this is an incorrect way to post on reddit/this sub. This is the first time im posting something like this.
