In a last-ditch effort, Spike had grabbed onto the caboose’s rail and vaulted onto the back. Out of breath, he thought to himself, ‘Thank Celestia I made it.’ He looked towards Canterlot with absolute optimism that Fleur would still be there waiting for him. ‘Fleur, please wait for me.’ He then looked back only to see Rarity in tears. He felt bad for her, but he had no regrets. This is what he truly wanted.
As Spike rode the train, all he thought about was what he would say once he saw her again. He would tell her how much she means to him. How she was the one for him and he would never let anyone get in his way again. He will be more adamant about his decision to love her. He would look out the train and think about his time he spent here.
“It has been one hell of a week. She came into my life out of nowhere and snatched up my whole soul away. She’s a high-class pony who doesn’t feel like she is. A pony who knew when to keep up appearances, but behind closed doors is really more of a child than she lets on.” Spike then looks at a fleeting away Ponyville and remembers Rarity.
“I’m so sorry Rarity. None of this was really your fault. I even felt deep down that my plan would’ve probably have failed anyway. I didn’t expect you to not only fall in love, but she stole my heart before you claimed it. Looking back, I was most at fault since I didn’t try harder to stay with you even when you needed me. I apologize for that, but I only feel sympathy and not empathy. I loved you before, but I have moved on just as I know you will as well. You’re not going to recover quickly, but I hope you do. Actually I know you will Rarity. You were always stronger than everypony ever imagined. Time for me to let go however.” Spike said as he noticed how close he was getting to Canterlot.
Spike then began remembering the silly events that transpired as he was in Canterlot with the dance, the secret spot to see the fireworks, going out shopping, Fleur kidnapping him to go on fun rides together, and even though Spike was distraught most of the time, she kept coming back and bringing a smile to him. She knows that in the beginning that she was doing it intentionally for Fancy, but she was genuinely happy and he could feel it now in hindsight.
Spike never left the caboose of the train, but just took in the breathtaking sights holding tight to not fall off and watch a great portion of Equestria. Maybe one day he can go exploring all different parts with Fleur. He’s sure she has seen a lot with her line of work, so why not explore even more together.
Once the train finally pulled up to the Canterlot station, he walked off to the platform and noticed Fleur there already as if she was waiting for him or rather waiting for the train. She had bags and everything like she was ready to depart. She noticed him staring at him and was overcome with emotions. Her normal demeanor was broken as she charged at Spike. Spike still being undersized however was swept off like nothing by Fleur. As the tender embrace lasted for what seemed like forever as they stay their hugging, laughing, and full of happy tears.

This is the story's new end without breaking the original's sequence. Anything after this point was the original ending I had intended long ago.

The reality that was around Spike finally stopped.
Spike was home. Eyes full of tears, soulless, and depressed. He took one final look at the window outside his bed and said under his breath, “If only she didn’t stop me. If only Rarity let me go and I didn’t miss that train.” Spike stayed awake the entire night looking at Canterlot with the calendar next to the window reading one week later.
As he lay there awake, he began replaying the true events of that day. Rarity holding him back with her magic. When he broke free she leaped onto his back preventing him from boarding the train. She was crying, babbling, saying how she just couldn’t let him go, but all he felt was the life being drained from him as the train moved on.
A quick flame of anger lashed out as he got up and he separated himself from Rarity, but he did not hurt her. Just glared with a cold glare and walked away. Rarity stood there paralyzed, like a pony frozen in the tundra by the anger and the lifeless eyes he had. She had never seen his eyes that way before. No pony has ever seen Spike’s eyes like that, but her.
Spike remembers going to Canterlot the very next morning, but it was too late. Fleur had already moved on and to where? No one knew. Her agency said that she went on an extended vacation to wherever and departed on the last train. The sickening feeling in the pit of Spike’s stomach only got worse the more he tried to look. A whole week of searching and he came back empty-handed. Now he lay in bed wondering what to do next and reminiscing about the past.
Meanwhile, Rarity was also replaying the events in her head, but all she could see was Spike’s eyes. She remembers when she finally came to, he was already gone. Rarity thought to look for him, but those eyes flashed into her head. Rarity was scared, filled with so much fear not for what Spike may do to her, but fear that they will never be close again. She realized that she was selfish and may have ruined his happiness. All these years of friendship shattered by the raw jealousy and selfish need she had. Rarity had been very generous before, but Spike was the one thing she didn’t want to give up.As Rarity lay in her bed looking at the stars out her window, all she muttered was a single regret, “Why didn’t I let him go…”
