Take in all info at lawyer and don't get emotionally involved in decisions.
I know this wedding is a big thing to you. Can you honestly answer why? Is it because you will miss the family or are you worried it signifies things are done? She will be seen without you? Or are you worried she will be looking to spend time with someone else there?
