"I'm X-Tra Confused"

At the local flea maket today I found this 1980's French Marvel comic called Spidey, which I have absolutely no idea why it's called that since there's not an appearance of Spider-man in the comic outside of an ad for another French comic with him actually on it on the back cover.

What it is, in fact, is X-Factor #3, which I believe is the first appearance of Cable as "Baby Nathan".

Looking at this story again got me to remembering "why" I gave up on any of the Marvel X-Men type titles back then.

The original Jean Grey "Marvel Girl" had died during the Claremont/Byrne run on Uncanny X-men, but had been replaced later with a clone (?) of named Madelyne? She and Scott Summers get hitched and produce a child named Nathan, who in reality, grows up to be Cable, who then goes back in time and met The New Mutants?

Then, over I think in The Fantastic Four, Ms. Grey (aka: "The Phoenix") has been found on the bottom of the ocean in a cocoon, and is resurrected and rejoins The X-men, but as Marvel Girl again instead of Phoenix? Later, she and Scott get married, right? But, what happened to Madelyne??? This whole storyline got me pretty confused. So much so in fact that I ceased buying any of the X-titles, and outside of the more recent events that unfolded in the Milligan/Allred run on X-Force and X-Statix, I couldn't tell you what's gone on in any of them for the past 20 years.
