My son has just got engaged to his very lovely girlfriend of three years. They are marrying next May. DH and I lover her to death and get on very well with her and her family. From this forum, I know that MILs can act badly and do the wrong things and be very annoying. I don't want to be that woman. I have already told my DS that it is their day and I don't want to interfere and won't offer unwanted advice unless I am asked. Can any recent brides tell me what I should and shouldn't do to make sure their day goes well?
