She may have forgotten to add you to WeChat, but she just saw you in another software and remembered you. She wants to chat with you, make friends, or trouble you to meet if there is anything. After all, meeting you at least means it's not fraud. Even if she cheated your feelings, she didn't cheat your money. If you don't mind adding WeChat to meet you in other software without chatting, you can send her a message on WeChat and ask her out. Only when you take the initiative can you have a story. Besides, she offered to meet you, which means that you still have a place in her heart.
