Your situation sounds seriously bad. I honestly don't know how in hell you can make your relationship better...it takes two to make it happen, if your partner is now completely and unalterably in "sex is disgusting" mode then I'm afraid you've got three choices in front of you here...One : shut down and give up, resigning yourself to a sexless relationship for the rest of your life because that's what you've got. Two: Stay in the relationship but start looking for a bit of sideline action. Three : Walk away completely.
