1. Love hate realtionship is a complicated relationship in which there are always two sides. The first side is the common attraction and love for one another. The second is the "hate" which is actually an attraction so strong that our human heart can sustain, it is based mostly in fear.
2. Love hate realationship can emerge from a partnership where both people have to work in the same space or office. There is an attraction but there is also no privacy in which each to be alone. So it becomes something like...I like you but I cant be with you all the time, so I hate you that way we can be in the same space without being together.
My parents started as a love hate realtionship.
