I think it depends on the reasons for the hate. If the bad feelings are because of an incident, argument, disagreement or what not. What is the cause for the bad feelings? Not asking, just something one should consider. Does the person have a legitimate or irrational reason for what they've done to cause you to hate them? Sometimes it matters, sometimes not. I think many factors come into play and also the depth of love/hate you feel for someone. I've loved people and hated the way they treated me but I still love the person I believe they are underneath. If you are struggling between the two feelings it may just be that you love them in spite of their faults.
