It could be just the basic instinct. The feelings can be passionate and crazy, but in fact both people may want only sex. And after it all the misunderstanding starts, and once infatuated lovers will find out that they have nothing in common and sometimes they don’t even know what to talk with each other.
Another variant is when people lack support, care and attention to their person or they just scared to stay single. Being with someone can be a habit when one simply got used to the other. It can either be a sick addiction or some self-interest. People call all these types of relationship love just by mistake or trying to conceal the true nature of it.
But than what does real love look and feel like? Maybe it’s when two people seem to know each other for ages and even in their previous lives. They can go on talking and talking and conversation never lacks topics and never gets dull. Or people don’t have to say anything because they understand each other without words. And those moments, minutes and even hours of silence are never uncomfortable. True love is when partners complete one another, when they’re together it’s peaceful, the whole other world with it’s sufferings and problems doesn’t exist and nothing even matters.
