Backstory: My FI parents are divorced. He does not have a good relationship with either of them. His mom gave us a good amount of money towards the wedding but wanted nothing to do with planning etc. His dad gave nothing - no interest in wedding either. My parents paid for 80% of the wedding and have gone above and beyond in supporting FI and I for years. At the wedding how do we thank the parents? I cant, on principal, thank his parents in the same way I would thank my own. FI feels the same way. At the same time I will not be rude. How should thank you's happen during our reception?
(Thanking them for raising the man I'm marrying is OUT. So is thanking them for welcoming me to their family.) Any suggestions?
