Does Friendship between a woman and a man exist?

Friendship is very a complicated phenomenon. People can't give exact definition to it even nowadays. It is one of the most popular topics of talks. People try to make friends with others, because it is a natural need of every person. One of the greatest things about friendship is that it is an important instrument of socialization.
People make friends with people they see often. Friendship may appear at work, at school, in Universities, and other places where people spend a lot of their time.
Friendship appears suddenly and sometimes people don't even notice that they make friends. The usual friendship is a friendship between persons of the same sex. But sometimes friendship of a woman and a man is stronger than friendship of people of the same sex.
But some people say that there is no real friendship between a man and a woman, because one of them loves their friend. It is true partially. The problem is that when time passes mutual attraction and affection appear. Women and men fall in love with each other. And the natural instincts play an important role in it, because people naturally feel attraction to the opposite sex and consider every person of opposite sex as a potential husband or wife. Not to mention friends, after all they have so much in common, they do the same things, and they have the same interests and know the traditional behaviour of each other in this or that situation.
There are a lot of examples when a man and a woman were friends for a long time and got married. But there are also a lot of examples when a friendship between a man and a woman was ruined after one of friends fell in love with another person.
Friendship between people of opposite sex is very complicated and depends a lot on the differences in psychology of a man and a woman.
As it was already mentioned, one of friends is always in love with the other. And what's the use to argue about it. There are a lot of examples of it. So, when someone is in love __________he/she is ready to do everything for the person he/she loves but when he/she sees that the person he/she loves starts to date another guy/woman, of course he/she looses any interest. And the friendship can't last any longer because one of friends just looses any interest to friendship and relations.
Simple jealousy plays an important role in relations of friend. A person understands that his/her friend doesn't pay so much attention to him/her as before.
Not less important thing is jealousy of a husband or a wife to the friend of their wife or husband. And the common belief that there is no friendship between a woman and a man is guilty.
But of course there are a lot of friends that have great relations and tell about their love affairs to each other. They are friends and have great relations helping each other and loving each other. So, don't be afraid to make friends, it is one of the greatest wonders of human relations. And friendship is worth being experienced. It will help you to feel good every day.
