Messed it up?

Whilst working and studying I've been having feelings for a coworker, she has moved on to another job now but because I don't actually have an excuse to talk to her in person I'm quite lost. We do have eachothers socials but I didn't ask her out and I didn't ask her for her number while we were working and I regret it. Too concerned with being unprofessional and all that talk about not dating at work etc. It was a contract job too. What can I do now? We did get along well and she did in fact display indicators such as heavy contact, excessive touching, asking personal questions, dating life etc.
There's no way she'd give me her number over socials becuase she's one of thes people that values in person exchanges and privacy. She doesn't give it out online. Knowing this, I still asked her for it thorough socials and unsurprisingly, she said no.
I don't respect myself for not having the guts to ask all this while we worked together. What options do I really have left? It's not about sex, I do actually like her.

As a former girlie, I say just start a convo on the socials, cause then that trust over socials is built and then be like “oh is it okay to have your number” and so on. I know it’ll be hard cause of how I’m assuming you don’t want her to get the wrong idea, but if you don’t try, you don’t find out? Right?
