I have a crush on someone and he knows. We even talked day and night before and he also said he likes me yet we were both confused that time because he still loves his ex. I waited. But there are instances that he shows me he likes me too and instances that he shows me he does not. However, he flirts with my best friend but she has a boyfriend. I am more worried about them than me. I wanna know your thoughts, should I stay or stop?
