I am having 2 bridal showers, one is being hosted by my mother and one is being hosted by my fiancé's mother. My future mother in law has asked me if I would invite my fiancé's stepmother to the shower being hosted by my family to avoid the bad blood between them. I've asked my mother about it and she told me she'd do it only of my FMIL would attend as well, which defeats the point of inviting the stepmother to my families. I feel like the my FMIL should just invite the stepmother to hers since it is her side of the family's shower and not mine. I'm not sure what to do about it. Any advice?
