sad,disappointed,down

Today i got this kind of feeling. this feeling is back again. i owes wan to hide my feeling behind n when i wake up all gone. End up i stil cant make it. Need to speak n talk out OR type here. Last few mth my fnd told me tt he got a new gf. On tat time i don have any feeling at all. Just thk well,sure one day he will find new gf too n i will find new gf too. But im confuse now. When one of my fnd told me tt he saw him wif one gal n wan me to make sure tt i reli forget bout him. I thanks a lot to my fnd cos they honest n direct to me. BUT im not honest n direct to myself. This is a big problem. I keep thking why my relationship owes end like tt? Wat d i do wrong till i get this kind of reply? Anyone can answer me,d i do somethg wrong?
