I lost my besties after 20yrs of friendship

She kept saying that she was happy that I was getting married and that she wanted to help me with my wedding planning. Well, every time I ask her to accompany to a bridal expo, she would say "yes" then cancel the day of. She would say that she wants to help with my DIY projections, then the day of "something came up". Sabotage my FDIL's bridal shower at a beautiful restaurant. Then thru me one at a store that was open to the public during my shower. Ladies, remember this, during your wedding planning journey, true friends will be there & the phonies will die out quickly. Be true to yourself! BTW, she showed up at my wedding & hit on one of my good friend husband during the cocktail hour, another crazy biotch that bit the dust. Have you experience this?
