Love has lost its original meaning. The totally dedicated, all giving, honest lover is seldom found/seen. All that is noticeable are people who are emotionally unstable, with very little compromise and easy-give-up attitude. Having a boyfriend or girlfriend has become the social trend. Neither sex wants to get into a committed relationship as they see more disadvantages. The love of today is a immature emotional dependency, very spontaneous and short lasted.
People think more rational and practical while choosing their mates. The emotional content, if any, is fast disappearing. The top parameters are monetary, physical, IQ and social aspects of the person. They have replaced things like long term compatibility,true affection, compromise, determination,forgiveness and moral value.
They say "Girls are pure at heart"-meaning, they are able to forget flings faster and get on with life.And "Guys are emotionally unstable" - meaning, they need to get a girl before the girl gets a guy (and they usually do). So when we are all hard-coded this way, it is not surprising how things have turned up.
People fall in love for want of attention and not the giving of it. It is an irony that as children we are encouraged to act mature and as adults we decide to act childing just to get this attention. The time lovers spend together may have increased, but much of this is to test the other persons patience, availability or honesty than anything meaningful. Else it will be to reiterate the fact that they are still in love. The underlying meaning is long lost and in my view, will stay that way.
