According to my experiences, nowadays, most of the boys can't accept the reality. Maybe some boys disagreed with what I said. But this is my opinion. I'm sorry if its hurt the boys.
If we rejected them, they can't accept it with their open heart. Why ? I don't know. Well, I already rejected two boys, and both of them same. Cannot accept the decision I made. I hope one days boys will be matured enough to think what best or not for them. There are some reason why girls don't accept them in their life. So, understand and accept it !
