Guys, do you flirt with other girls in front of your crush?

[Anonymous]

Guy visibly likes me and flirts with me often, but a few times, I caught him flirting with my sister. He stares at me frequently and stands close to me a lot. I don't make it obvious that I like him back, I just smile but don't say much when he approaches me. Guys, do you flirt with other girls in front of your crush?

Could it be possible that he is just nice and dont have intrest in you?

Lmao, who hurt you?

It is just a suggestion you know
Usually if a guy is truly interested in you and he is a decent guy he goes to you not your sister
So i assume he might not be interested

i mean an 18 or 19 yr old would but I don't know why a man your age (25-29) would wanna play mind tricks even up to that age
