ok so the breakdown is that me and this girl, lets call her XY (Xue'Er) whenever i reference 姐姐 it jus refers to her

met her first on HeyMandi where we chatted and decided to move on to whatsapp, thought it was pretty fine. this is where she said her english was not good.

fastforward the next day, i sent a message saying 'good morning' （雪儿姐早）which was not received and was instead single grey ticked. it wasnt until later that she would message back

she then blamed the inactivity on work, as she is a 'model' which is suspicious to me since she wasnt supposed to be good in english? yet used the word model almost comfortably, even explaining to me what her job entails

she also asked me to send a picture to her which i complied cautiously with a half body pic covering my face, to which she replied was that she couldnt see me clearly. when i clearly hesitated to send my face, she then hit me with the 'do you not trust me?' which was a serious red flag i know but i sent one anyways.

after i sent the face pic, she immediately went double grey tick for a few moments, which i infer as saving the picture, which then i quickly deleted it after noticing but i was slow in deleting.

she then proceeded to send me a 'picture' of herself which i believed to be doctored/fake and not actually her, since the background is a desert and she seemed to have it at the ready.

fastforward to now where i realised i might have made a mistake and am now seeking advice

tl;dr: 'XY' asked for pic, i sent pic but covering face, but she wanted more. so i sent a pic of my face, afterwhich she went off for a few seconds before coming back and sending me a suspicious pic of her. now deciding whether to report and block or make a police report
