The Jealous bridesmaid :(

My wedding is next month! I am marrying my soulmate and I chose a small circle of close friends as my wedding party. All of my friends have been supportive and then there’s one! From the beginning I’ve felt jealousy from her because her boyfriend of 4 yrs have not proposed and my fiancé proposed within 1.5 years! I didn’t take it personal at first because I understood. But things have become very toxic . She used my bridal shower as an alibi to cheat on her boyfriend, fast forward the following month gave her boyfriend an ultimatum to propose and then finally he did. Throughout my entire wedding planning process I found out she’s been divisive, trying to tell me she took credit for planning bachelorette activities all by herself and spoke negatively about another friend when that friend actually came up with ideas and spent a lot more money. Now she’s flaked on the bachelorette which was significantly well budgeted because I covered a good amount to make sure they didn’t have to spend much. Lied about having covid and not being able to go , i tried to reach out to get a refund for her by sending the test to let the people know and she said oh it’s negative now but still can’t go. And through all this she wanted to mention how her wedding planning is going now. It’s exhausting and I am not sure if I should remove her as a bridesmaid.
