I know I will die in regret

and I believed you when you said I better think about this cause if you leave I will never see you again , like a fool I told you I didn't care and we are done ..I sit here now wishing I could say sorry some way some how. I did you so wrong and it's killing me even tho it's been so long , how can I fix this ide give anything for your touch your kiss , your warmth and love I so miss ,, unfinished business
