i m devastated--i feel like my life is over *UPDATED*

as many of u know i have posted about my boyfriends hesitance on getting married and we had talked and worked things out...i was not going to pressure him and give him time to see what he wanted from life being that we r only 23...well on saturday we had a fight about something really stupid, and then it led us to saying horrible things to each other and then he said he wanted a break from us and was going to move out of our apartment to live at his friends house. we have been together for 3 years and we have lived together for 2. I can not believe this is happening. he is my whole world and i love him more then i love myself. i can not imagine my life without him in it and now we have not talked since saturday even tho he promised to call last nite to talk more about things. i m scared that this is the end, i dont know how im going to live day to day w/o him when for so long i lived my life with him, i feel like i wana die, the pain is that bad. i feel like i have lost my best friend, my lover, my everything..the ache in my chest is so bad i could just kill myself. even when my father passed away the pain did not feel this real. i went to my moms ghouse to sleep b/c i can not bare the thought of being in the aprtment i share with him alone. everything is a reminder of us, and i just wanna die..i dont know whats going to happen to us now, maybe he just needed some time to think, but i m devastated and just wanted to share what has happened. thanks for all the past advice. -Michelle

UPDATED--
me and him talked yesterday and he told me i m his best friend and he loves me but he needs to b alone to find out where he is going in life and that he is sorry he is ripping us apart. he definitly loves me but unfortauntly i can see that for now, it is not ment to be. he will b moving out by the end of the week and we r splitting the things we owned together. we r signing a contract to prevent further problems. i m so heart broken but i m trying to cope and just think positively. thank you for all the kind words and fm's i really appreciate it all. i m terrifed to go back to the apartment that we shared, that is covered in pics of us and b there all alone so im staying at my moms until he moves out and then she is helping me redecorate. deep down he is a wonderful man who has a lot of selfishness to overcome and a lot of growing up to do. and i pray and pray that maybe one day we will b in the same place in life. my heart aches with this unbearable heartache but i hope with each passing moment that things will work themselves out.
