How do you know if a guy likes you if he’s a flirt?

Why would a guy in his 30s not settle down… he still flirts around.. he’s accomplished , educated, very charming and can get good looking chicks… actual models..

how could someone know if it’s genuine? And ALSO why doesn’t he settle even if the girls are perfect
