Help!

Please be patient and read my story to get my question:

My fiancé and I have been together for 2 years now. I live in a community small enough that you can’t sneeze without your neighbor two doors down hearing you. So I can’t ask this to anyone close to me without it spreading like high school gossip.

My fiancé had a fling with a girl, named Krissy before him and I dated. Her and I were kinda close and we continued to hang out as him and I got more serious. At the time my fiancé was working at Krissy’s moms business. Krissy and him would work together, but she would flat out flirt with him. (I trust him completely. She wouldn’t do anything either) but it made me uncomfortable.

She would

- Ignore customers to watch him make food and flirt

- Cut me off while having a private moment with him to make a joke about me

- Talk down to me

- She slept with his best friend and still flirted with my fiancé, in front of us, while I was carrying his child

-Her “joking” is very hurtful judgment

(Also this just might be her flirtatious personality, Idk, i just don’t mesh well with people like that)

I let it go and moved on. Later on after my fiancé left their business, I began to distance our friendship. Before I began to distance myself, I had mentioned I wanted her to be a bridesmaid. But that was also before I got engaged. We haven’t hung out, chatted or had coffee in almost 6 months.

I’m not basing my judgment on those events. Our personalities just don’t match and she hasn’t always been the best of friends. So my question is, is it wrong of me to tell her I no longer want her to be a bridesmaid?
