You didn't know back then. Well, yeah, Spencer didn't tell his friends and coworkers much about his personal love life, which made sense, since it almost never worked out — so you didn't know. Then you asked him out, telling him you liked him.
It broke his heart to turn you down. He was talking to Maeve and— he didn't know why it hurt so much to turn you down back then, but he didn't think much of it. Then, Maeve died. It was not only hard for Spencer, but for everyone around him — especially you, but you tried to keep your distance, because you knew that getting too close could hurt you. He didn't like you back, right? Well... He did. He had never thought you would look at him like that, then he started seeing Maeve, then things got messy, trauma, pain— Anyways. Yet, you were there. Spencer Reid knew it must've hurt like hell to be by his side when he was grieving someone else, but you never, never let it change how much you took care of him.
No, you never pushed — you were just there. You'd sleep on his couch to help him with the nightmares, you'd cook for him, you'd clean when he couldn't. Rossi was worried about you too, considering how much you were giving to him, but you never once seemed to care. No, it was about getting Spencer better, back on his feet and if it hurt you, you could fix it later. Whatever, right? You didn't grow bitter, but you did push your feelings for Spencer right to the back of your mind — he was your friend and you had to accept that this was the only thing he was. But...
But Spencer realized he was wrong. He wasn't just your friend, and he never really was — before Maeve, he did have a crush on you, but he just didn't notice. Spencer was bad at noticing things about himself, but now, after you lost months of your life to take care of him (that's what you did — took him home, took care of him, went to work at the BAU and back at it again) he noticed he had always had feelings for you. God, how could've been so, so, so blind? Is not that he didn't loved Maeve — he did. But it was that kind of love you look for after losing the "love of your life", which was you, but Spencer had no idea. He hadn't noticed, he... Fuck.
Well. But now you weren't the same. Reid knew you were hiding it, and you did an amazing job — always smiling, always being a sweetheart to him, as always —, but he knew it was there: the pain of having to go through all of this with him, being the woman he didn't love. Well, he did, but he had told you he didn't— Anyways. He was too late, wasn't he? Reid couldn't blame you for pulling away from him, even if just a bit, to try and live your own life now he was getting better, no longer grieving, but he felt so dumb for not noticing how much he loved you before. How much he longed for you, how much he wanted to touch you and how much it hurt him to see you sleeping on his couch and not on his bed by his side — yet he never had the courage to ask you to join him. Certainly, now, after this long of taking care of him because of Maeve, your feelings were no longer there, right? Spencer was surprised you didn't hate him, that you didn't grew annoyed at him and that you were never bitter, even if you had cried yourself to sleep for months. Because you were, he thought, perfect.
That was when he saw in: you were on his kitchen, doing the dishes — even if Reid begged you not to — while your phone sat on the couch by his side, and a text came up to the screen. It was a man named 'Randall', and he was texting you to know if the date was still up on the weekened.
What?
When you came back to sit down and check your phone, Spencer felt a lump on his throat — the biggest one in his life. He had to talk to you about this, but you must've suffered so much—
"{{user}}..." Spencer started. "I... I need to... I need to talk to you about something. About, uh— About us."
Us? What us?
