A/N: Thank you for the over whelming response to this. Due to All the people asking I have now decided to expand this one shot.
Roy landed on the floor of the foundry with a loud thud.
"Hey watch it man. You trying to kill me or something?" he shouted at Oliver.
Oliver just grunted and walked over towards the training dummy. Digg helped Roy of the floor and nodded to him to get cleaned up. When Roy left Digg walked over to Oliver.
"You know you have no one else, but yourself to blame."
Oliver just continued to punch the dummy.
"Look I know it hurts, but you cannot move on from the pain by punching everything in sight."
"I know, "Oliver sighed. "But you tell me how am I supposed to move on and forget about her? She was the only light I had in my life and now I've lost her as well."
Digg had no idea about what to say to Oliver. The answer came from an unlikely source.
"You haven't lost her!"
Both Oliver and Digg turned around and saw Roy glaring at Oliver.
"You haven't lost her, she still cares about you."
"ROY" shouted Oliver. "This has nothing to do with you!"
"I know, but you are forgetting that I'm the only one here who understands what you're going through. You lost Felicity and I've lost Thea."
A pang of guilt ran across Oliver, remembering that it was his fault that Thea had left Roy.
"Roy I'm sorry..."
"No shut up Oliver! You are going to listen to what I have to say today. Thea left me because I couldn't be honest with her and now she wants nothing to do with me. You lost Felicity, because you were too much of a coward to tell her how you feel about her. What, did you actually expect her to wait for you to finally remove your head from your ass and see her true worth? She even came up to you when Daniel asked her to leave with him, hoping that you would give her a reason to stay, but no, the great and powerful Oliver Queen even had to sacrifice his feeling for her. Do you know how much it hurt her every time you did something like that? It made her feel that she was not worthy of you."
With that Roy just grabbed his red hoodie and stormed out of the foundry. Oliver just stood wide eyed at what Roy had just reviled. He could not believe that his stupid sacrificial actions had hurt his beloved Felicity.
Digg finally stepped up to Oliver.
"The Kid is right Oliver. You have been a huge asshole to her. But there is still time for you and her. All you need to do is go to her and tell be truthful for once in your life. And maybe let her make a decision about the two of you, cause let's face it, you ain't been doing such a bang up job."
Oliver spent the next few days thinking very hardly about what Roy and Digg had said to him. Was it possible for him to get his Felicity back? However all thoughts of getting Felicity back were pushed to the back of his mind, when Malcolm Merlyn began his revenge on Oliver, buy using Thea against him. It was a long and lengthy battle which they eventually won, but the cost was a high cost that Oliver had to pay. In an attempt to distract Oliver, Merlyn had kidnapped Digg's son and used him to try and get Digg to betray Oliver. Roy, Digg and Oliver battled hard to get him back and only won, when Thea finally realised that Merlyn was truly evil and was only using her.
Merlyn was taken away by A.R.G.U.S to pay for all his crimes and Thea had used all of Merlyn's money to takeover Queen Consolidation and had it back over to Oliver. But the main loss was Diggle, who had quit the team saying that he could no longer fight alongside Oliver. He could no longer allow his son to be used like that again. Oliver accepted his reasons and promoted him to head of QC security as a thank you.
It had been four months since the Oliver has seriously thought about Felicity. Oliver was in his office, when Thea walked in.
"Hiya Ollie"
"Hey Speedy, what brings you here?"
"Well I was hoping that you were free for lunch"
"Give me a few minutes then I can join you."
Thea smiled and looked around his office.
"You know Ollie there's something not right about this place. Something's missing."
Oliver looked up and his heart fell into his stomach. He realised what was missing.
"Sorry Speedy, I'm gonna have to take a rain check on lunch. I have somewhere I need to be."
"Ollie where are you off too in such a rush?"
"Seattle."
Oliver climbed on to a rooftop opposite Felicity's apartment. He had just landed over an hour ago. Whilst he still had no idea what he was gonna say her, he just needed a glimpse of her. He looked into her window and saw her on the couch reading something on her tablet. He was awestruck by how beautiful she looked in just a pair of sweats and a man's shirt. He looked closely and realised it was his shirt she was wearing. The one he had given to her when she was shot by the Clock King.
Oliver's concentration was suddenly broken when he saw Daniel come and sit next to her on the couch. He pulled a small black box out of his pocket and opened it up. Oliver heart stopped beating. In it he saw a diamond engagement ring. He saw Felicity let out a scream and launched herself at Daniel and pulling him into a hug.
Oliver suddenly turned around no longer able to look at the scene in front of him. Felicity had made her decision. She had forgotten all about Oliver and moved on to a bright future with Daniel. Oliver slipped back into the shadows, vowing never to look back.
