Is this your fiance's brother who just died?Mainly I think it's an emotional response that i'm thinking he'll regret and I know my fiance is going to be devastated. Everyone in the room is going to want to jump out the windows because here they are partying when this poor bastard has been put through the ringer. Brother in law gonna talk to him, he agrees it's going to be bad for all.
The wife and I personally didn't, but we did meet online so our situation may be a bit different. I know some girls are all about the omg its our 16 week anniversary and shit, but my wife was never like that. So unless she has been bringing it up a lot I'd not bother or do something simple like get her flowers to surprise her. If she has mentioned it more than once then you may want to plan more ahead.Delay the wedding and wait out the cancer? I kid, I kid.
On a serious note, for the non-married gents (or those who dated for years before getting married), did you ever make a big deal of "anniversaries". Today is the 3 year anniversary of, uh, first hooking up with the special lady friend. We don't make a big deal of birthdays or holidays or whatever else, in general. Just wondering if other couples do or did in the past?
I think this is the proper way, if you can get the mother in law to chime in also. Maybe have a picture of the deceased / assign him a chair on the main table, with flowers.Brother in law gonna talk to him, he agrees it's going to be bad for all.
