Now that you put it all out there in one piece, their relationship just seems so vague. Hopefully Pirates 5 will clear it up.

That's the point. It's pretty much for fans to piece together themselves. Either that or maybe use it as a plot for a prequel novel(ex. The Price of Freedom) Plus, it's one of those things that gives filmmakers the "more freedom" they need to tell future stories with.(otherwise, well, we wouldn't be able to say that Jack's trinket or Ragetti's eye were some of the nine pieces of eight)

But Jack and Angelica's past relationships doesn't really need to be discussed in P5 unless if it's needed for the story. It was needed in OST because Angelica was introduced in the film, therefore needed some backstory to fall back on(in the film, the visual guide, etc). So as far as I know

Though oddly enough, the idea that Jack's lace was a gift was improved by Johnny Depp himself - the script never showed this!(only the ring) From my research, back in making DMC, the lace was only said to be "a gift from a Spanish lady"...and now, thanks to Mr. Depp's improv(and the interview seen here), we now know who that Spanish lady was. And because of that, it brings up the suspicion that Jack and Angelica met up between CotBP and DMC(as the lace was never part of Jack's costume until DMC). But bear in mind, nothing is confirmed as of yet!
