What cause one to build hate to the person is because the other person posseses an attitude/behavior that you dont want him/her to have.........but that does not mean you dont love that person, in fact it is because of your love that you wanted him/her to be the person you wanted to be..........however-----when this feeling of hate/anger become so strong it also becomes so unhealthy for you both that it may create a hole in your relationship.......(possessive as you may be come)
you have to understand that each person is created unique and is not perfect....each has its own flaws that may be unacceptable to you no matter what your feelings for that person.......your attempt to change him/her depends on how you love that person........during the process its either he/she change or you change your standard and views on certain issues....or give up that person..........
I love you BABY.............
