This girl I’ve been seeing for a few weeks wanted me to invite my closest friends over so she could meet them. We played some drinking games, and I noticed that my buddy was hitting it off with the girl I’m seeing better than me and her were (banter, playfully giving each other s**t, strong eye contact, super competitive with each other, ignoring me for most of the night, checking each other’s bulge/butt out, even poking his butt and laughing). We agreed the previous date although we weren’t boyfriend girlfriend, we wouldn’t not entertain other people. Should I be worried, and are they attracted to each other?
