What do you do when someone dosen't like you?
Depends on why they don't like you. If you've wronged them in some way, you should try to atone for your wrong. If it's just that they don't like you for who you are, ignore it and keep being what you know you should be.
leave her or him because where there is no feelings than their is nothing
play up your good features, and wear something sexy,but casual
kidnap him, trap him in ur basement, torture him, and then ask "how do u like me now!!!!!!"
here's the thing. Not everyone is going to like you or approve of what you do. What matters is going to sleep at night with a clear conscience because YOU approve and like YOU.
