Love has reasons too or to be precise it has attractions, attraction by beauty, attraction by intelligence, attraction due to the way we feel comfortable with them, attraction to the standard of living they could offer us and so on. Once the reason is lost, then it is a choice for us to decide whether to stay in a relationship or leave.
