What Do I Do ???

What have i done to deserve this ? Doesnt he love me anymore... Doesnt he miss me anymore like i do...? Doesnt he cry for me day in day out .. Like i do ? All those promises of staying together forever... All those talks of never leaving me... Those talks of our future together..  Was it all a lie ?? Was all this a lie from the start ?? Was i so blind in his love that i cudnt see it all ?? after making so many promises...after showing so many dreams of the future.. What is my mistake in all this ? Just bcoz of the fights he is ready to give up this relationship of 3 long yrs..Where we shared joy and sorrow togethr..been with each other at good times and bad times..made so many memories to cherish a lifetime.. Is his love so weak to let the fights over power it ? Is it so easy to be so hard on the person whom you love ? If so then why am i not able to do it ?? Why is it that evrytime i think of him its only the good times i remember.. why cnt he realise that the fights are not worth to give up on this beautiful bond we share.. I opend up to him...told him even the darkest of my secrets...trusted him with my life..being with him i was all chirpy and happy and now that he has left me im all lost ang going insane..Don't know what to do..what's right and what's wrong... Just the thought of the break up brings goosebumps to me.. Why im made to go through this hell... I loved him whole heartedly...And this is what i get in return from him... How can he be so harsh on me...doesnt he realise what he is pushing me towards... I really cant take it anymore... I dont know what to do... Feel like dieing.. Dont wana live this life if he is not with me... Coz he is my life.. Without him i dont live but just exist wit no meaning to my life..
