dude, they dont not like you because youre too available. some guys are judges mostly on attractiveness and some want a girl who is kind and understands life but if a girl aggressively shows interest that doesnt make me go, oh shes too available. It makes me think oh this girl isnt an immature complicated type improves chances, playing hard to get is so overrated just do whatever the fuck you want, be yourself, be confident in yourself. If a guy doesnt like you back then you guys wouldnt have a good connection in the future, if he is the type to look for someone who has the same mind set and interests and you match that criteria and you are yourself then you win
