My fiance and I are not having bridesmaids or groomsmen at our wedding, so we really wanted to involve our families as much as possible in our wedding/processional. As such, we asked our dads and my brothers to wear suits to the wedding (preferably black, but we're flexible). My dad and my brothers didn't have a problem with our request, but my fiance's dad is flat out refusing. He says that we won't be any less married because he's not wearing a suit and thinks it's foolish that we would even make such a request. He told my fiance that we need to reevaluate our "priorities" if what he wears to the wedding is so important to us. He also has been telling my fiance that we should be spending our money on things other than the wedding. Since his family isn't helping financially at all, I'm irritated that he's giving his opinion on the whole thing to begin with. Overall, my fiance and I think his dad is being very disrespectful and we're not sure what to do. We feel like his dad just doesn't care about our day and what it means to us. The thought of looking back on our wedding photos 40 years from now and seeing his dad there in his casual clothes while the rest of us are dressed up makes us sad.
My fiance and I play by his family's rules when we're visiting at their house. Since we're not married, his parents make us sleep in separate rooms. I don't necessarily agree with their rules, but I respect them because it's their home. All we want is for his family to play by our rules on our wedding day. Is this too much to ask? We really don't feel like we're being out of line.
