Friend never invites me when she's going to a bar/clubbing?

maybe she see's you as a "Not so much of a party" type?? Hate to be mean but maybe she sees you as boring, or that you might clammer over a guy shes hanging with at the clubs. I do not know the cirstances of course b/c I dont know you, but talk to her ask why after inviting her to all your get-togethers, why she wont do the same for you. It is the only way to get it straightened out, but if it dont work then hang out w/ new friends.
