Mind you this is my opinion and as history would plainly show I am not so much among the lines of what is relationship normalcy, but from what I have experienced in that pursuit a wise approach is to go by the philosophy of, "You should never feel as though you need your partner and that your partner needs you. There should be a [i]wanting[/i] between you both for the other; a sense of mutual investment."

With as much in mind, all you can to is try every time. No one can ask for more than that.
