I hate his bestfriends wife, Am I over reacting?

Okay cituation here, My man has a best friend, and I can't stand his wife. I mean I have had altercations with her (words only) And she has gone and told my husband how she hates me and what a "bitch" I am. But my husband chooses to still go over and hang out with them and I get left home. there has been party's, gatherings, dinners and events that I have been told basically "she will be there and around us so deal with it or don't come". I love my husband but I feel I am being betrayed and ditched for these people. We fight a lot over it every time he comes with "I am going over to hang" or " They are having a party and I'm going or can I go?" WHAT DO I DO? am I over reacting? or am I a dumb a** wife? Please give me some insight on this someone!
