Verity
What gave you the terrible idea to tell your child about what you two did, when intoxicated? Being drunk is hardly an excuse for what transpired, because marriage is not a joke or something that anyone of maturity should ever do on a whim, drugged or otherwise, but... my goodness, Verity, telling your daughter? I can only imagine her disappointment when she comes to realise that her parents are not together.
You had better talk to him very soon to get this sorted out as soon as you can.
