by the way, in my opinion there is absolutely nothing wrong with falling deeply in love in a short amount of time. there are MANY long-lived, rich, and beautiful marriages out there between people who knew within days or weeks that they had found the love of their life. only you know whether this man is your soul-mate. only you know what you have experienced with him.
but the man you love will no longer be able to care about you or your children, if he doesn't get clean. in fact, it is likely he will come to hate you.
so...do what you have to do.
