text: I think it very much depends on how long you have been going out.  both of you are from a relationship, and my worry is that the possible raison you want to move in together is because you both miss sex. Once a week is not too bad for a relationship!  My advice is to take some time before moving in together and I'm sure you would want to balance your religion with your personal life.  If you don't at the end you will get hurt and loose the confidence of your friends.
