This is my first time writing and I must admit I feel a little self conscious, but I am at my wits end and could use a little advice. I live with my partner of 7 years and her 17 and 12 year old BDs. I have 2 adopted children of my own who are not here all the time (from a previous relationship) My 17 year old SD is a straight A student, has a job is very active in school and a good kid. She has been living with us fulltime becasue she can;t stand being at her BFather's house. Unfortunately she is a slob. Her room is horrible, disgusting ( and I can deal with a lot), not to mention that she doesn't do anything around the house, she says she's too busy and she has a tendency of getting very defensive. I feel as if she has a sens of entitlement about her. My partner does not know how to follow through with any type of discipline and so I end up being the disciplinarian at times. My problem is that I feel so resentful toward my SD, she treats me and my partner as if we are her slaves and it's getting to me. I realize that this may be normal teenage behavior, but I can't help the resentment. Does anyone have any advice? THANK YOU!
