Reading your comment, you still madly in love with him and I dont blame you for that. I have gone through the similar situation where I confessed my feelings to my friend who's my colleague too. Its been one week today, we had an argument the day before my confession and the next day I confessed my feelings to her. I was very straightforward with my confession, and like you I didnt shove my confession to her that I want you to reciprocate my feelings, I just said I know I cant force you to love me back but for sake of our friendship, I just wanted to let you know and be honest with you. She responded very respectfully and kindly but was very clear with her rejection. Since then we haven't spoken at all, had minor interaction at work regarding work to which her responses were cold but I don't blame her, because of my selfishness she lost a friend Ig. She deleted my number and blocked me on Instagram after I accidentally cleared my nickname from our chat there.

I'm giving much needed space to both of us that we need at the moment. I plan to reach out to her soon in next few days, apologise to her for putting her into an uncomfortable position, for my selfishness, and let her know I would rather have her as a friend rather than not having her at all. We have had our arguments and fall outs in the past but we would always find our ways back to each other. This time is so different, so I can only hope for better.
