>>1 Don't do it. I don't know what the hell other people are saying, nor do I care, but let me just tell you this: Don't do it. If you feel like you want somebody to die, why the hell are you still going out with them? Just dump them casually. Say, "I don't like you anymore, sorry." If they decide to be all emotional and crap, "Either you give up or I will never speak to you again."
You can't go out with someone you hate. Obviously, if you grow to dislike them, you two don't fit. Either he is obnoxious or you are obnoxious, and the match therefore doesn't work. Don't try to force yourself into a relationship that just is not working. I understand that forcing yourself to eat it until you like it works with food, but not with men. Don't force yourself to like them; dump them and continue until you find someone you can honestly open up to.
It's ridiculous to keep going out with someone because you hope you might start to like them.
Life isn't some anime; you don't magically grow to love people you've come to hate. Waiting won't do any good; it will become weeks of your life that you'll never get back.
Patience and time won't work miracles despite what your teachers say. Miracles don't happen. You have to use your own head to get what you want in this world.
Keep trying. If you don't like them, don't go out with them. Save yourself for someone who you won't feel like strangling. There's no point in loving someone you want to kill.
