How it feels to loose some one you really love

Today yes today is the one the worst day of my life . I just lost some that i really loved some one who was everything for me . Today i lost love of my life my boy friend . We were in relation with each other from last three years and today i just knew about his another girl friend as well .

So what happend to day when i went to university as usual we both had a cup of tea and he told me that he has got some important work to do and i was having a class as well so i told him yes sure you can do that and once you come back we will have a chit chat and he went and i went to the class when i checked into the class my friend aliza told me that sir is not coming today and we dont have a class today and we are free so we both decided to go out and have a cup of coffee but no in university cafeteria out side that . Once we got inside the resturant and order two cup of coffee for our selves she told me that see who is sitting with that girl and once i saw that my boy friend was sitting with another girl i was just like confused for a moment and didnt do anything than i call him and asked him where is he so he said that i am with my father in hospital and i really got hurt that how can some one whom you love the most can do something like that to you and i just said ok when you are back let me know i am in the class .

So it was like almost an hour that he came back to university (once i finished the call i came back to university directly )
he started saying directly hy ailiya sorry i am late but you know what i was stuck in hospital and has to arrange all the things i just started crying and said you know what i know each and everything you dont have to explain it anymore and please dont talk to me . He started explaining things to me but i didnt hear and came back to home and now he is texting me again and again and saying sorry so what you guyz think what should i do ? looking forward for your suggestion guyz
