<human>: Can you summarize the given text in a few sentences?

I've developed a crush on a guy I used to work with. He was new and when I first saw him I thought he was really good looking but didn't think much of it. We worked in different departments but I would usually see him in the morning since he would have to walk through my department. We would say hi and trade quick glances. As time went on he would start the most random conversations. At this point I started to realize that he seemed to me interested in me. After submitting my two weeks notice things started getting a bit crazy with finalizing things at work, so I didn't get a chance to interact with him much during my last week until my 2nd to last day, we were alone in the kitchen and it felt like he wanted to say something but didn't. I kept thinking to myself say something anything, start a stupid conversation, I was about to ask him random dumb question but again I froze and didn't say anything. Looking back there were so many chances I had to try to get his number but I didn't.   

So I was thinking of writing a quick note and having my friend give to him just saying "Hey sorry if this comes across as weird but I had the feeling that you may have been interested to getting to know me more, if you are here's my # text me sometime, if not sorry about the confusion."

Do you guys think this is a good idea? Does it come across as creepy or desperate?
<bot>: Should I write a quick note to my ex-coworker giving him my phone number, but not sure if he's interested?
