What'syour biggest disagreement with your fiance?

Yes we have are disagreements! The main one is about his ex wife. She runs all over him and he seems to just sit back and let her! She will call and tell him he HAS to come pick up their daughter even tho its not his weekend, he dosen't have the gas to get there or he has to be at work in an hour and even tho he tells her no she will tell him that he needs to figure it out.. and then he will and he will either go pick her up or have his parents do it ( his daughter not his ex) It drives me bonkers.!
