do you honestly think that your relationship is so "special" that you will actually last?
get fucking real. people change constantly and what are the chances that you will both still be compatible. what if one day a person comes into your life by chance and he or she is the most wonderfully perfect person for you...what do you do then with your already existing relationship? we cant honestly think we will be attracted mentally and physically to one person for the next 50 years of our lives can we? is the idea of open relationships really that bad?
