I don't quite know the feeling you're talking about
But, I guees that if this person was so important to you, s/he wouldn't do whatever s/he did to cause you pain !! there's certainly a reason and a good one !! I'm pretty sure about this !!
Have talked with him/her about this ??!!!
p.s. don't try to hate him/her , it'll only get worse!!
"Love breeds hatred which breeds revenge"
don't follow this way or you'll end up like Sasuke!!l
