There’s no closure cuz this ain’t machine stuffs and she’s just a colleague, ur relationship with her is just a friend, don’t put all the eggs in one basket and put all hope on her only then u move on, move on now and proceed to other girls

Maybe she forgot, or she don’t want to reply u immediately cuz she don’t want to sell herself cheap, maybe she liked u that moment but don’t now, but whatever, u didn’t make things worse, yet , because u two are still under the same company
