give her time by just simply telling her okie i will give you a space, if she does not retrun., that means.. she is not the right one for you. i know its hard because you invested time, effort, yet
its like this..
it is better to love and express love even if you fail sometimes than not love at all...
just focus on your self for a while... then also think.. maybe this is a sign that you focused your self too much on her than you..
always remember you can't love too much if you dont focus also on your self..
