I lost my soulmate, and I don't know how to get him back.PLEASE READ!?

I am SO depressed. I am madly head over heels in love with this guy, who was my best friend for 3 years...and we recently dated for a year. We knew eachother so well, were so comfortable together, and loved eachother so much due to the length of our friendship, however, there were major dating complications. We have completely opposite lives. I have a day job, and hes a singer in a band, so he works in a bar 5 days a week. We are also 17 years apart in age. We knew this would lead to issues based on the fact that our lifestyles are so different, but we loved one another so much that we didnt care. I have NEVER felt so connected, so close, so comfortable, and so in love with anyone in my life, and neither had he. We had fantastic chemistry, a strong friendship, and a very pionate and loving relationship. Unfortunately, it wasn't enough to save us from the fights and the stresses of our lives. We started arguing a lot about his job and behavior at the bar, although he always reminded me how much he adored and loved me and that it was just work...it wasn't enough to keep me content and unaffected. Needless to say, we broke up a few months ago because it just wasn't working. I am WAY more miserable without him than i could have ever imagined, and i not only lost my soulmate and lover, but my best friend. I don't know what to do. I've been desperate and basically begged for him to come back, I've gone to a few of his shows to try and talk to him, but everytime I see him it breaks my heart all over again. He always gets teared up and sad when he sees me too, but consequently is very cold-shouldered and pushes me away. He told me that all of the wonderful things and memories are tainted and will never be the same because of all the heartache. So now what?! I don't know how to live without him, but you can't force someone back into love with you. I'm afraid that if there really is one person for everyone, that HE is that person for me, and theres nothing I can ever do to win him back. He just keeps saying he wants time and needs more time to heal and move on...so clearly he isn't trying to have space so that we can eventually work things out again. I feel empty, lost, and numb....what do I do now?
