Y is it so hard to hate someone you cared about?
It may have been a lover, a close friend, a not-so-close friend, even someone from your family, but it was someone for whom you cared about, somewhere along your life. And that someone did something to you that you really hated, that really pissed you off, that you considered disrespectful given the feelings you had.
You decide to sever the ties that connect you to that person. If possible, you will not speak to him/her. You will have no interaction whatsoever.
You are really hurt and you hate that person. Not the person per se, but his/her action(s). But aren't people defined by what they do?
Still, hate is very different from love. You cannot choose who you love, even though sometimes it would be great if you could. But you can choose to hate someone. And maybe the answer to my question lies here. When you choose to hate, you dedicate yourself to doing that. But how committed are you in doing so? For how long? If you cared for the person, do you really want to hate him/her? And what if you still bear those feelings? Are love and hate compatible?
If you are a normal, regular, sane person, no, they are not compatible. And love will always win, whether it takes one day, one month or one lifetime.
So, don't waste your time hating someone you care(d) about, because in the end all that hatred will disappear and you'll end up realizing you wasted your time and maybe lost the opportunity to have a good relationship with someone.
