Long story short--my mom does NOT like my FFIL. I could go into details, but it would be really long and boring. FFIL does not know that my mom does not like him, because they live in different states and really don't see each other that often, so when they do see each other, my mom plays nice.Wedding is very soon, and I know my mom is very anxious/stressed about it (I'm the first of her kids to get married, she was very recently hospitalized for bipolar disorder, wedding planning has been less than stress-free, etc.). So I'm absolutely terrified that she's going to break down if my FFIL acts like he usually does (bossy and condescending). How much did your parents and FIL's interact on the wedding day? I have them seated at separate tables. I hear that on your wedding day, you are running around so much that you don't really spend all that much time with any one person--is that true for your parents as well?
