Make sure you include yourself in any decisions being made. Even though you would not really care about the color of the flowers, what the guests should be wearing, just make sure you're there when she makes such decisions. If she ever asks for some advice or opinion, make sure to give her an honest answer, or you can just say that whatever she likes would be fine with you.
When talking about your budget, make sure you talk about it with her – this is very important as this would limit the type of wedding you will have and this will affect you both so it is just essential that you will discuss about how much you will be spending for your wedding. This is depending on your budget and the financial help that your family might give you for your wedding day so you need to know the total amount that you can spend on your wedding day.
Be supportive of her whether in bad or good times. She might be frustrated at times with the planning that she might have breaks – should this happen, take over if she needs and wants you to. If she was trying to find out prices by calling different locations, do that for her.
As the groom, you might be at a lost with the whole wedding planning and have no clue what's happening – this is but normal, but if you want your partner to be happy – follow the tips mentioned above .
