Love the Title
First off, One of the reasons I scrolled through the list of stories in the humor section and picked yours to read was because I loved the unique title that grabs your attention right away. Your characters were well described and each their own, which is the pitfall for many writers. The character development was also spot on with Nicole and most importantly, I genuinely enjoyed reading this story.
Read the story now
I'd suggest going back and proofreading your story and also having some other eyes do the same as this will likely catch most grammatical and basic errors. Also, there are some things repeated a lot throughout the story like Leanne's reasons for jealousy.
My main issue was probably Andrew. The reasons I understood from the story of why he and Nicole drifted was Cora, him not wanting to disappoint Nicole with Cora, and Cora wanting the wedding to be all about her. This disappointed me as through the duration of the story, this was the question I was waiting for the answer of. To me, those reasons don't explain why Andrew would forget to invite his family to all these important events until the last minute. I would love a better explanation for the drift and why Andrew waited so long to show Cora off. Obviously, if I missed another reason, please let me know.
Overall, great read which I would recommend others to read
