If husband and wife are not living together more than 8 years will this ease the divorce procedure?

Me and my husband are not living together since more than 8 years now, the marrainge is not a successful marrainge and I have expressed this many time to my husband, I have been mentaly upset at many times but as i took care of my only son i handled my self and moved on. he keeps on coming to visit and be in touch with everyone in family but I have told him very clearly that I want a divorce since nothing between us is working. he wants to just strech this marraige. we dont agree on anything and no relation at all between us. I have been thru mental harrasments many time in first 3 years of marrige, during pregenancy and after child birth it got increased. I have survived everything. my son is now 17 years but I am seeking to get relif from this marraige. my husbund is palying emotional and not letting me go. he everytime say sorry and wants me to go on like this lifelong. whereas i am total indepedent from start and do everything on my own. I feel I have to move on. Can you suggest will I get divorce easily in this situation? there is no reason, no love, no attachment in this marraige from any angle.
