Not in love with each other? This scenario is the best. When two people are not sexually attracted to each other and are not interested in a romantic future, then there's no tension, which means that a successful relationship and friendship is possible. According to a recent survey of Dating site match.com 55% of respondents reported that they have a lot of friends of the opposite sex to which they do not experience sexual attraction.
Men and women can be just friends, when they have many common interests. Additionally it is helpful for both parties to have the opportunity to consult with members of the opposite sex, and look at situations "from the other side".
No wonder the Internet you can find expression — in my opinion my friend, if she doesn't have anything to complain about, would complain that she has nothing to complain about!
