Bad date gone worse

Not too long ago I met and started seeing a woman named Susan. Susan's a total barfly, but I figured there had to be more to her than clubbing. My bad. Earlier today we talked about going out this evening and she said she’d call me. She did--and said she was going to Sullivan’s with some friends. She said she didn’t want to leave me hanging and said she’d call again. An hour later I called her and she invited me to come out there. So I got up, got dressed and went. When I got there she introduced me to her friends and then ignored me. I tried to make conversation and she would cut me short, and finally she said it was really a girls’ night out. I tried not to get upset (why, I wonder now) and told her if she didn’t want me to come she shouldn’t have invited me in the first place. She said she wanted to see me but she was out with those friends, etc., and didn’t know what to do. I told her I was leaving, and she didn’t even try to stop me! Time to move on...
