I agree with the others that this can all go very well and you will go straight back to how things were, but i would once again like to be devils advocate and just say that memorys are not always how they appear. how many times have you had a fond memory of a type of food and after several years tried it once more and your tastes have changed, or rembered a favourite spot where you used to go and once you return over time relised that its all been changed? i just hope you are not holding on to memorys of a good time in your life and hoping this man will bring them back as things don't work that way.
things change and you must be prepared for that, although i'm sure you already are.
thats not saying things can't change for the better either!
hope you have a great night and even better future!!
good luck
