My fiance informed me that his father does not want to wear a tux at our wedding because he has "somewhat of a "social phobia." When he used the words "social phobia" I immediately assumed that he also does not want to be introduced with the bridal party at reception. My fiance informed me that is not the case and that FFIL told him that he would do the "announcement" part. Huh? I can understand if he didnt want to be "announced" because of this "somewhat social phobia" but this isnt the case. He just doesnt want to wear a tux and bring "attention" to himself. FFIL said that he will be wearing a "casual suit." Whatever that means! I can't help but think that by NOT wearing a tux, he WILL be bringing attention to himself but thats just my opinion. Geez, even my Uncle, (uncle/Niece dance) is wearing one. Overall, people arent going to drop, gasping for air over this so who cares right? My fiance does. This is the only thing that he asked of his father. Period. EVER. FFIL gives all of his time, attention and money to my FSIL (38 yrs old) and this "little" request isnt too much to ask. Now, instead of it being just about a tux, it represents something much more for my fiance.
I know we cant dictate what others wear, and I would never attempt to but really....he has to wear something so why not a Tux for a 7pm wedding! My anger is building and now I feel that this is just so disrespectful. Im sooo pissed off yet still confused!!! Also, FFIL and his fiance, for the last 4 years (since fiance's divorce), have "secretly" spent Thanksgiving by my fiances ex. wife. Something that devastates my fiance.
Btw...my fiance and his father have a "wonderful" relationship. I also get along with this man. I must say because of his "somewhat social phobia" I have only been invited to their (FFIL and fiance) home 2x in 4 years.

Point being, I've managed to accept he is the way he is (and thats "just him") but this Tux thing makes it difficult to not take things personal....I am really beginning to. I know there is nothing I can do so Im asking you to help me put this
into perspective and minimize what is going on or not going on?
