common problem for guys............. until they get the other one ........especially after 1st love......... don't worry friendl!its not only you ;there are lots of guys facing such problems.they just can't forget their beloved ones.the moments they share ;the promises they made eachother cronize their discomfort.they think they might be guilty for what they have done(i.e. they should not be apart). But u know kapeel! life is not only contained within the boundry of love.as everybody knows,love is a part of life;not the heart of life.divide lifetime into parts.may be that part was for love....the past ,but one should think about the present.the career,another more important in life(especially for friends of twenties)......consider it at present.that GF is "ex" now, and she will always be ex.i bet .......she will never be back.so look forward.......a glorified world is waiting for you .utilize your present,the most valuable time............
