Show me how to get over the breakup blues.... ?

I broke up with my boyfriend of 3 years (we're 25.. so its not like its a high school romance) a month ago. I thought things would get easier, but instead, it almost hurts more. Over the past three years, he has gotten more and more religious, almost to the point where I've watched this man that i love so much turn into someone i don't know. With his religion, unfortunately, has come judgement (due to his italian catholic MOTHER who despises me because i'm not christian) on all of those who aren't religious. I know that we wouldn't work with him being like this, but I still can't picture my life wthout him. We were supposed to get married, have babies and take trips together. I still love this man, and wish it would work. Ultimately, its my decision... but life is so empty without him in it. What advice can you give me? I don't know what I beleive.... but i know i don't want to judge people the way i've been judged. He isn't catholic, he says... but he's so caught on the bible being absolute that anything that strays from it is wrong, and that isn't how I want to live my life. I thought we could compromise, but i'm so resentful at him for having made religion the great divide after all of the hurt his family has caused on ME with it.... that i feel like he is ripping us apart with it. He practically lived with me and I haven't talked to him or seen him in a month. It's drivin me crazy. I dont know what to do to NOT think about him. What helps to get over a broken heart? how do you give up on the future you thoguht you'd have?
