I have been with my husband for 18 yrs and married 15 yrs. I have two adult daughters that have never caused any problems in my marriage, they love my husband and they are very nice and supportive. They are independent and away living and working in other towns. My husband has three adult daughters, they are in their 40's, they never accepted me as their dad's wife and never will.  They absolutely hate me and they have done everything in their power to get me to a point where I will pack my bags and leave their dad.
