I'm Confused About The Ending Of Roseanne...?

I know I didn't get it at all. I just leave it as David with Darlene and Becky with Mark and Jackie was with this price guy. Darlene had a baby girl,Becky pregnant and sadly Dan died of a heat attack. Didn't like the part of Dan dying he never got to spend a lot of time with his grand babies. They also had a 4th baby who wasn't very old.
