you will be fine and so wil he. it is not an extended period of time. a wedding is a happy time and you should enjoy it. every "parent" needs some down time. the week will be gone before you know it and remember... absence makes the heart grow fonder. i be he will be thrilled to birdie pieces when you get back!!
it is very hard though to leave your buddy but you will be back before you know it!
