Ok then - going back to your original question: why does it surprise you that men can see past a woman's exterior appearance? Is it because you are unable to see past a man's exterior? And if you CAN see past a man's exterior, why would you assume that others can't do the same?
The only explanation I can see for your whole post is that you're unbelievably shallow
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
