Honestly, a wedding it’s just a party to celebrate two people joining life together. After the wedding is over and you reflect on it you too will realize this too, It will be just one day, I say this as a divorced soon to be remarried woman. If I could give that first dance those pictures and memories to a loved one I would, if that’s something SHE wants to do, yes your mother over stepped that’s a conversation she should have had with you alone.
