The wedding date hasn't been set yet, neither has the location so it is only a possibility that we might not attend. If she does get married at christmas either here or in Australia we can not go. We have spent $7000 on air fares that are non refundable or non transferable. No matter what happens we will be at WDW this christmas and she has know that for a long time. Seen as her parents will be paying for most of the wedding I doubt they will allow it to happen without her brother there. To me it is the fact that she has even considered it (she even pointed out to me that we would not be able to attend so she is aware of that fact), something I would never have done (it didn't even enter into my head that she would not be my bridesmaid let alone not be there altogether.) When we were discussing the date for my wedding if she had said there was a date she could not make I would have not got married on that date has her being there was important to me and Pete.
She is a very caring person and I really think that when she thinks about it she will not set the date for when we can not attend. Like you have said Ohannafamily, she probably was not thinking at the time. I mean she only got her ring today!!
I am probably getting myself upset over nothing, and I think she will realise that her family want to be there with her on her special day, whether she gets married in the church she grew up in (where her dad is still the church organist) or in Australia (which is quite strangly an hour away from where my family live in Australia!!)
Like I said earlier I am actually quite ashamed of myself for feeling this way. I guess I just always imagined that when she got married I would be there.
