I'm a girl and I've had a couple of guys I've " hated" but then they started small chatting and were careful about wat they said and never even JOKINGLY put me down... That made me want to talk to them more ... They also smiled more which rly got me when u talk to her make sure u smile a lot more ( at the appropriate times)
You get a girl who hates you to like you by first establishing the reason for her hatred. You need to then correct the things that she hates about you. Let her know that you are sorry for everything by being serious in the way you carry out yourself. You can also buy her presents and request her for an out together.
