Weddingbee boards

I think it kind of depends on the relationship between your FI and his step mom, and you and his step mom. 

I'm in the exact same situation... dealing with FI's dad and step mom, and mom and step dad. It's a lot of inlaws. :) I feel like I could definitely get away with doing this stuff without his step mom because she would know that it would be too weird to have both of them there. As long as I made an effort to do something with her too I don't think she would mind at all. BUT- Fi's step mom/mom aren't really like competing for his/our attention or anything. Everyone is pretty content to just ignore each other forever. heh.

ouch, that's a rough decision to make! What did your FI suggest? What kind of terms are the women on? If they're on speaking terms, and you really want to do the dayspa thing, I'd say just go for it and hope they're on good behavior. Afterall, they're bound to end up at a certain amount of wedding related events together.

If they're not on good terms though, or have an level of cattiness, I'd say either do the spa with a more selective group or drop it all together.
