Unfortunatly they didn't had a chance.. He was 'merried' with a stripper.

Jackie and Hyde never reconcile. A new crop of writers was hired, and they ignored, dismissed, and dismantled the previous seven years of the show and characterization. Throughout the season, Hyde behaves entirely unlike himself and treats Jackie cruelly, especially in the episode “Keep Yourself Alive” where he calls Jackie "bitch" and says she's "real bitchy". He also lets her fall into a lake and laughs at her afterward.
The first episode of the season “Bohemian Rhapsody” teases the audience into thinking Jackie and Hyde might get back together. Hyde returns home after spending two weeks in Las Vegas. Jackie says, "Steven I am so sorry about what happened in Chicago. I was alone, and I thought I lost you." Hyde says, "Yeah well, I can see why you thought that." Jackie says, "Look, why didn't you tell me sooner you wanted to get married?" Hyde says, "Because I wasn't sure I wanted to. And now that I've thought about it, I'm right, I'm not ready to be married yet."

Jackie feel hope at Hyde's use of the word "yet," then Samantha arrives and claims she is Hyde's wife, married during a drunken wedding in Las Vegas.

The newly-hired season 8 writers decided to seperate Jackie and Hyde's relationship on the show and broke them up permanently. People involved with the show, however -- including the actors, such as Danny Masterson, and That '70s Show's long-time director David Trainer -- have stated in interviews they don't believe this is how Jackie and Hyde's relationship should have ended.
David Trainer once called season 8 "an alternate reality," and a fan asked Danny Masterson on his radio show, "We want to know what you thought of season 8 of That '70s Show... what you thought about your character and Jackie breaking up. Did you not like it, or did you just not care that they broke up?" Danny replied, "Oh, of course I cared. I didn't like it. I hated it. I hated all of it, but there was nothing I could do, you know?" He also confirmed that he thought Jackie and Hyde "should have ended up together".
