dream fragment

I was in my old house when I was a child. There was a party going on. My x girlfriend who I was thought I was in love with was there along with my brother and some other people who I had no idea who they were. There was around 12 people total. I can't remember how I got here although I do remember I took some type of long walk through a forest. Sadly I can't remember that part. Once I get in the house I see my x girlfriend which I try to ignore. She also seems to be ignoring me which makes me some what sad. Then I see her paying attention to my brother, laughing, and falling over him. This also made me some what jealous but rather than letting her know I simply found someone else to chat too. I do remember trying to talk to her as well but her responses weren't solid.
