Ask the Countess: Con-friend-tations

Dear Countess,
I've been grappling with conflict, regarding two opposing groups of friends. Essentially, one "crowd" is comprised of my college friends, and another of my new homestead and they have begun to "merge." While I am happy that everyone can get along, the more that the old and new pursue friendships with each other, the less included I feel. Is there a polite way I can confront any of my friends to express this discomfort?
Thanks,
Distressed

Darling Distressed,
You may be giving off negative vibes. I would say you need to check your confidence scale. Jealousy and friendship don't go hand in hand. Learn to silence your negative talk and pump yourself up with positive thinking. Remember friends are your friends for a reason. Relax and smile, it really does effect how people feel about you.
Cheers

Dear Countess,
My husband and I are throwing a party this weekend. We have a friend that we barely speak to, but the last time we had a party we included her on the guest list. This time around, we didn't include her, since the last time we spoke was the last party. This afternoon one of our party guests bumped into this person and asked them if they would be at our party! What to do? Should we apologize (which might be a little awkward), invite her, ignore that it happened? I'd appreciate your advice. I thought of you when I heard what had happened. Thanks for your help!
Laura

Darling Laura,
I'd say it depends on how much you care about your friendship with her. If you like her, the more the merrier. If not, pretend it never happened. Thanks for thinking of me. Have fun!
Cheers
The Countess
