I've only met my fiancee's parents a few times so I really don't know them all that well except for what my fiancee tells me about them. However I know they are wary of any partners that my fiancee and his brother bring home. So they have been polite but not overly warm to me on the few occasions we have met. We aren't going to be spending the holidays with them because of my work schedule but get-togethers and family functions are inevitable. And now with a wedding to plan I have no idea how much I should involve my future MIL, how I should even broach the subject on if she wants to help/be a part of it, and how to start building a relationship with both of them.
