If I comment "Gorgeous" on a woman's pic whom I am talking to since past 3-4 months; and in reply

It means thank you she appreciates the compliment, chemistry takes time if going to happen, well that's my opinion lol

Could do... Follow that one up and see what happens.

Its a gesture appreciating your respond.
It takes time to build chemistry with someone.

I think it means shes lovibg how you look at her.
Ask her out and see possibly?

Might just be she loves that you called her gorgeous.

A way of saying thank you and I live your comment.

Just tell her you like her ffs

yes, 😍 indicates her pleasure
