What do I do now?? :(?

ell my husband came home tonight and told me it was over, he wants to seperate. What do I do? I am a total wreck! I havent eaten or slept in 2 days, i have smoked a whole pack of cigarettes since 8pm. I asked him to hug me and he wouldnt do it. I have begged and pleaded with him to give it another shot. He took his wedding band off this afternoon. I have completely lost it! He is acting almost cold but says he is trying to make it easier on me no hugging i actually got him to give me a kiss. I know I am making it hard but how do you change over 3 years of habit in a day? I knew it was coming we been having problems for awhile but i thought we could work through it like i always do. He said neither one of us are happy and we need to make ourselves happy before we can make anyone else happy. We spent too much time trying to make the other happy we neglected ourselves. Now I am going to have to tell my parents today and hope they let me and my kids move in. We are going to keep our joint account for now and i will still pay all the bills until things get squared away. I dont know how to deal with this. I want him to be there and comfort me but he is being so distant. Again trying to make it easier on me he says. He wants us to still be friends. how can I do that when I will always want more! He is the love of my life! He has 4 kids with 3 girls and he wants us to be friends cuz the other girls are money hungry bitches! I dont know what to do or how to handle it!
