Relationships that start by duping a partner don't end well. Now, I'm dating a guy I met at a picnic my friend organized a month ago. It is very anonymous and people often make cruel remarks they would never make in person.
Something must have gone wrong. While this is certainly important for a man who wants his own children, or for a man who does not care for children, this is completely ridiculous. In short: they understand your life better than most.
