One of the Futurekind shorts the system out, filling the room with the rocket couplings with deadly radiation. Jack is enlisted to fix the couplings. While Jack is inside working, the Doctor admits he abandoned Jack purposely because of the immortality Rose granted to Jack. Jack readies the rocket for launch.
Jack was shot by a Dalek and then brought back to life by Rose, Rose couldn't control what she was doing so she brought him back to life forever, Jack is now immortal. The Doctor wasn't comfortable with what had happened so he ran from the scene leaving Jack behind on Satellite 5.
Consequently, the Doctor abandoned him in the year 200,100 aboard a space station orbiting a Dalek-devastated Earth. Stranded, the former Time Agent had to use his own devices to catch up to the Doctor.
The doctor leaves because he doesn't want to watch his friends die while he stays the same. He says so himself so why would he leave jack? Yes, jack would age but he wouldn't die and knowing him, he would keep going until he was a head in a jar.
Discussing whether his character could ever find a soulmate, John Barrowman refutes that Jack "likes everybody, and his love for each person is different". He believes that Jack does harbour romantic feelings toward the Doctor, but "would never take that beyond infatuation" and "would never let the Doctor know".

Who was the Doctor's one true love?
1 The TARDIS
Perhaps not a character on Doctor Who, but surely the Doctor's greatest love throughout all time and space is the TARDIS. Far more than just a machine, the TARDIS is a living being and is the only traveling companion that has remained with the Doctor throughout all their adventures.
To some, companion Rose Tyler was the greatest love of the Doctor's life. He seemed to have a closer bond with her than almost anyone he'd travelled with before, and as time went on it was increasingly clear that she was deeply in love with him.
Captain Jack Harkness was one of the Doctor's foremost allies, but the Eleventh and Twelfth Doctors never met him. Why did Jack disappear until now? Doctor Who's Captain Jack Harkness was a longtime ally of Doctors Nine and Ten, but then he disappeared from the scene until his recent arrival to help Thirteen.
This isn't really a thread the show picks up on again; at the end of the three-parter, the Doctor asks Jack to travel with him again, and in Journey's End the TARDIS lets him fly her no problem at all.

Each, in their own way, was affected by their travels and became bigger than themselves. They all helped the Doctor survive, across space and time. But Rose Tyler did it first. She fell in love with the Doctor, and he loved her.
After the Tenth Doctor's hand was severed by a sword during the Sycorax invasion of Earth ("The Christmas Invasion"), the hand was recovered by Jack Harkness.
Settling into her new life with the Meta-Crisis Doctor, Rose later became pregnant and gave birth to a daughter. Years later, she was briefly transported to her original universe and met the Eighth and Eleventh Doctors, after which she returned to her family.
In the time period, only women and children were allowed on the lifeboats first. Rose loved Jack too much to let him possibly die, so stating she wouldn't get on before Jack meant they crew would HAVE to let Jack on if they wanted Rose to live.
The Doctor and Rose can never see each other again; both of them stuck in a different reality, a different parallel universe, with no way to cross between the two.
Clara is the future child of the Doctor and River who's had her memory erased. The two Time Lords must be up to something on their nights away from River's prison cell.
Clara was forced to face the Raven, killed by the touch of a Quantum Shade. However, death would not be the end for the impossible girl, and using Time Lord technology, the Doctor was able to extract Clara a second before her death, between one heartbeat and the next.
He spends over a century waiting to reunite with the Doctor, over which time he becomes the leader of the Torchwood branch in Cardiff. He later reunites with the Tenth Doctor (David Tennant) and Thirteenth Doctor (Jodie Whittaker) for further stints on Doctor Who.
There are perhaps a few reasons for this. The first is that Torchwood were aware of the Doctor's time-travelling nature. They may even have eventually learned of the exact order that his or her incarnations occur in. At the very least, they probably learned that it was best to avoid any Doctor unless it was the Tenth.
The Doctor loved River Song enough that he suppressed the urge to roam for over two decades. This is something he was never able to do before River, and has never done again since.
In the Doctor Who Confidential episode End of an Era, executive producer Julie Gardner confirmed that the intention was that the new Doctor did indeed say "I love you" when he whispered in Rose's ear. On screen, this character was only ever referred to as the Doctor.
It is revealed that when the Doctor whispered to Martha in the previous episode, he said: "Use the countdown." Docherty's betrayal was planned — engineered by Martha so that she would be brought on board the Valiant to rejoin the Doctor.
“I do know of rare, rare cases where a physician has unintentionally and unwittingly, over time, fallen in love with somebody,” says Bereza. “It was mutual, consensual and they went on to get married and have a family and be a pillar of the community.”
