After a plate breaks, is there a rule of thumb of when you can hit them back up or should you always wait for them to contact you?

I was thinking about hitting up an old fling recently just for the fuck of it because my city went into lockdown again and dating is extremely difficult at the moment. For context, we fucked a few times throughout the year but then she said she started seeing someone 4 months ago. Also, she’s been liking pictures that I’ve posted of myself on Instagram not sure if that indicates any interest - haven’t been liking anything she posts to give her any validation.
