Need some Legal advice in sg!!!

So after breaking up with my ex i was there for her for 3 months. She would spam msg me saying she miss me even came to my area and work unannounced . I would react with empathy eventho how annoying it was.

When she moved on she blocked me without closure. She said i could whatsapp her if its really important.

So when i was at my lowest i did spam msg her that i fell into depression and i need to talk to someone. I got a hold of her on a call. Well she just laughed at me . She did apologise but i felt it was insincere .

Since then i sent a few msgs , some last monday and few yesterday and the day before . Saying that if she could talk one last time to help me move on, i miss her but no threats ofcourse and i said its entirely up to her. Keep in mind she could just block me.

She replied saying she will report me to the police for harassmant and stalking? And she has eveidence? I dont know when i stalked her? If viewing her public instagram account is then i dont know what to say.

I deleted her number and moved on since.

Anyway should i be worried?
