what will u do if the person u will propose will say no to u?

in both the cases i ill not leave her,ill stay as her friend and try to show my feelings for her..

You should know whether or not they are going to say yes before you even ask. If you do not know if they will say yes then you shouldnt ask. Marriage should be talked about beofer a proposal happens and if a couple cannot express this to each other than they shouldnt be thinking about being engaged.

Well I would hope that if I proposed to someone it would be resulting from a steady serious relationship and I would not have to consider whether that person just liked me as a friend. If my significant other said no, I would really have to review our relationship and see what isn't working to make him say no.. and perhaps its not meant to be forever.
