I understand where you're coming from here. People should be honest about their intentions in a relationship. It is wrong to pretend to be only seeking a platonic connection, when what you hope is for that to grow into a romantic one.
That said, however, I think you should acknowledge that the best romantic partnerships grow out of solid friendships. When you have known someone for years, worked together, have mutual friends and family connections, you can skip over the deceptive impression management that occurs in dating.
When the friendship is solid, such feelings can be discussed without pressure, and the friendship can be preserved after the romantic fling does not work out.
But please don't promote the destructive myth that men and women can't be friends, or that feelings never change.
