Should we work out or problems or not get married?

my fiance and i are suppose to get married in 6 1/2 months. in the past two months he has changed. he works out of town 5 days a week and i take care of the house. i clean, but we have dogs and a cat. if the house doesnt look like it was just cleaned he will yell at me when he first walks in. he has threatened to cancel the wedding multiple times and has even called our priest. he has been lying a LOT. i rush home on fridays to clean before he gets home "at 8" because of "traffic" and it turns out he is at a bar for a few hours with friends while i am cleaning before he "gets home from work". also, he tends to fight "dirty". in an arguement he told me he could love someone who was fat like me. ( i have curves but not fat by any means.) he said some other nasty things and when we stopped arguing he tells me he NEEDS "female companions" because he cannot tak to me about things. he keeps apologizing for what he has said and done, but it is eventually turned around and is My fault. he has tried to apologize and make up for the fat comments, but it still hurts. the "female companion" thing really bothers me. i just don't know if it is worth working things out. i almost feel like a failure if i dont try and it will be embarring to have to make all the phone calls to cancel the wedding, but i just dont think this will work. i dont want to end up getting married then divorced. is it worth a shot at trying?
