We've got a really weird situation with my future mother-in-law. After nearly 30 years of marriage, she walked out (twice, actually) on my future father-in-law last year. She literally left him a note on her pillow and walked out in the middle of the night. Father-in-law was almost completely blindsided by all of this.
Needless to say, nobody in his family is real happy with her. Half of the family doesn't want anything to do with her anymore. My fiance has decided that he still wants to have his mother in his (our) life somehow, but he's less than pleased with her recent decisions.
To complicate matters, she had been involved with another man, and as soon as her divorce was final, she married him. Neither of us wants him at the wedding. Fiance's family absolutely does not want this guy at the wedding. Our concern is that if we only invite my fiance's mother, she'll still show up with him.
Is it possible to only invite her? And what should we do if he crashes the wedding??
Thanks!
