don't worry about your crediability or going back on your word, those things only mean something when you do them and make the wrong decision. growing up as men we always learn those are two big deals when dealing with the world, but the caveat was that you stood in the right, not just for you but for others as well. my only suggestion is that if you want this to work, show her and that is all, then stand in the good spot and don't follow what you did before just to set a standard. thats if you want it. its a big pill to swallow, those parts of the book are tough for me to swallow, don't be right just be there. sucks i know.
