How can i get a boy to like me

How can I get a boy to like me after 3 years

my recent ex liked/loved me for a year and half before we even started dating

I called her to confide and get my mind off of the pain from a breakup and she was always there for me, we built a strong friendship and it turned into love...

you cant get anyone to like you
werther they choose to like you or not is completely up to them
just be yourself and ask if he likes you
if he doesnt, its not the end of the world
