I am currently talking to a girl right now. She is 18 and i am 22. We met online and she said she is graduated from high school. When we met everything went super cool. On the way back she told me she is senior year in high school. I didn’t make it a big deal but she clearly lied to me. By the way i have a sister that is at the same education level with her (senior year in high school). If she was graduated from high school i wouldn’t make it a big issue. But since i know it bothers me. She told me i’m her first kiss and every other boy ghosted her. I think she manipulates me because i am an older guy and girls like it but i think i don’t want her anymore. What should i do?
