No wonder it doesn't fit

I've been fighting with this pattern for at least 2 weeks and have come to the conclusion that I just need to start over.  I've measured, remeasured and remeasured again, and decided I made the crotch curve to short and no amount of adding to the crotch points is ever going to make a difference.  Last night I added 2 inches to the back, which brought it back up to my waistline, but it threw off the rest of the waist edge, because I had such a sharp angle from the center back to the side seams.  I know I should have added 2 inches to the front too, but I don't need more room in the front.  I'm going back to my original crotch curve measurements from the first pair of pants.  I need to get the crotch curve figured out before I can even think of making other adjustments.  I found a crotch curve tutorial, and guess that will be my next step if I can't get it to fit right.  So as much as I hate to say it, it's back to the drawing board.
