Uninvite my friend to my wedding

Hi Glow Team,

My one and only bestest friend just (according to Dan my fiancè) cheated on Daniel's guy friend with another married man with kids. Here is the thing, she was supposed to be the maid of honour next Sept in my second wedding, and walk with Paul, Daniel's friend but Daniel advised me she cheated on Paul with another girl buddy's husband who has kids. On confronting her I told her she should not come with Lana's (her girl buddy's husband) as it is not fair on Paul her ex, who of course will be at the wedding because he is Daniel's friend. But I think she should not come along all together for being a sl*t. I am that pissed off all she could say was I am sorry. I used to work nights when I was 19 all up to xmas time with this girl, she was at all my kid's birthdays and she set me up with Daniel. So I ask, do I uninvite her cos she will come along with a married man or just let her come and keep her and Paul separate. Or does it not matter. The poor guy is reeling... and so am I..

Thank you team.
