Until Whitney acknowledges that she has a problem and takes steps to remedy that problem, there is no helping her.
Whitney is a vessel and at one time was a class act. What makes her "downfall" so hard for us as fans to process is because she was a class act. If it were some other artist, one whose caliber was less than Whitney's we would be less "disappointed" but because it is someone who is an entertainer and not just a studio artist, we are befuddled by this "Sudden turn" in her lifestyle. Now of course this might be a lifestyle that she had before Bobby Brown but we need something to say to make us feel better so to say "Bobby turned Whitney to WEED, COKE, CRACK, MAKING LOVE

(sorry could not resist) is a little easier for us to accept.
Whitney is determined to hold onto her marriage. In some ways I admire her because we have tons of other folks who marry and divorce before the ink dries on the marriage certificate or before they can eat the wedding cake for their first wedding anniversary. However I will not hold on to a man with all of that baggage -- drugs, jail, gap teeth, gold teeth, etc.
