TIFU by telling someone I have a crush on them

I’m a very honest person and always tell people to just tell it like it is, but I think I might’ve fucked up doing just that. I’ve developed a bit of a fascination that recently turned into a crush on someone at work over the past 6 months. It progressed slowly and there were a few moments where I felt that he might feel the same way about me but nothing concrete so I didn’t act on it until recently. We work together but in different departments. I know dating at work is a slippery slope, but I’ve learned that the only relationships that work for me are the ones where feelings slowly develop over time after being exposed to each other day after day for a prolonged amount of time, and well, I’m not in school anymore so.

We recently had an office party and as a company we tend to go pretty hard at these kinds of events. I was drunk and so was he and we spent most of the evening gravitating around each other but in a larger group. I made a few flirty remarks and he reacted positively. I thought I felt a vibe from him that night and even tested it a few times. I walked away for a prolonged amount of time to see if he would miss me and he did. He put his arm around my waist and asked me where I’d been. Later on in the night when we were sitting next to one another, our legs were touching and I tried to move my leg away to see if he would bridge the gap. He did. Multiple times. I even asked him point blank if he was single. He said he was. So I felt pretty confident when I asked him to come over for a final drink at the end of the night. At first he turned me down saying it was a bad idea but we shared an uber and he decided to stop at my place and come up instead of continuing on to his place. We spent a few hours talking about everything and anything and I impulsively asked him how he felt about me because he was still at my place at 4am and he had to work the next day. I told him I’d developed a bit of a crush on him. He said he’d figured as much but couldn’t offer me anything romantic. He’s had a recent bad experience dating at the office (so have I, it was something we told each other pretty early on) and he needed to be absolutely sure before pursuing anything but was enjoying this evening and would love to spend time together as friends. He kept reiterating the “friends” part. Now, I harbour no hope that he will change his mind, I respect the rejection, but I did also really enjoy talking to him and got a little excited at the concept of having made a new friend. We spent a few more hours chatting after that and I made a few racy jokes that I now really regret but it really seemed like we ended the night on a good note as we hugged goodbye. He encouraged me to reach out to go see a movie or something as friends. I really felt good about how things went at the end of the night and we texted a little after confirming that we both had fun and wishing each other luck with our respective hangovers.

Well, a few weeks have passed and I’ve reached out once at work to have lunch and got shot down. I texted once for a random question and didn’t get a response and we recently had a casual conversation at work that seemed to make him so visibly uncomfortable that I just stopped talking and backed away at some point. The man was shaking. I feel so horribly guilty now about this. I’ve disturbed this poor man’s peace at work and it even seems like he’s actively trying to avoid me. All because of my misreading a vibe and being impulsive. Is there anything I can do to rectify this? The idea that my presence makes him uncomfortable makes me feel awful and I wish I could take it all back. I never meant to introduce any stress into his life. All I can think of is just to avoid him/not text him anymore and hope he forgets all about it. I haven’t messaged him since and I’ve deleted his number so I don’t drunk text him down the line. Not that I would, but I really don’t want to take any chances and do something to make him even MORE uncomfortable. (Also taking a break from drinking for a bit, seemed wise)

TL;DR: told a man how I felt about him and it made him super uncomfortable
