Should I move on or is it rational to still be hurt?

I married my husband February 7th 2018 and on January 27th 2018 I was having my bachelorette party, and my maid of honor/best friend of 12 years didn’t show up because she told her Fiancé and parents that there was going to be people smoking pot at the party and they told her that she wasn’t going. At the time she was 20 and I was 21. Her birthday was the next day so she was about to be 21 also. My husband thinks that I should be over it by now and part of me thinks so too but it still stings bad when I think about it. The pot smoking was outside and before she showed up so we didn’t intend to have her just sit in the smoke... I need more than two peoples opinions. And I encourage comments of your own as well!! Positive and negative!! ⚖️
