My 19 year old StepDaughter recently moved in with us 3 months ago. Needless to say I feel as if my world has been turned upside down as my marrige and home aren't the same anymore.

DH and I have been together for 5 years, married for 3. He has two Daughters from previous relationships but they have never lived with us since we've been a couple (they've lived with BM's) and I have no children of my own. We've lived alone with just the usual visits and Holidays with SD's, etc. HOWEVER....having SD19 live here now is an entirely different ballgame.

Since having SD19 live in our home everything has changed. Firstly, SD19 has signs of developing something similar to "little wife syndrome" (always wanting her Dads attention and diverting it from me) and DH seems to suddenly be bit by the "Disney Dad" bug. DH seems to be at SD's beck and call....if she mentions something she wants, he buys it then or brings it home as a "surprise" for her later on. When going out to eat, he lets her pick the place, when going to the movies, she picks the show. You get the picture. Overall, it seems I have no say so anymore as DH is turning to SD for HER opinions and input on things and not mine.

SD purposely brings up scenarios and situations in an attempt to make DH jealous or go into protective Dad mode.....examples: that little game called what if, she's constantly asking DH questions like "What if I started dating an older man?" or pulling little stunts like wanting to go running late at night by herself so DH has a protest. It's getting quite obnoxious for me and of course, DH is totally oblivious.

There's a bunch of little things that have added up to all of my frustration....like the fact that I used to have to come into the bedroom to watch an NBA game because DH was strictly a football fan. SD loves basketball and suddenly DH is totally into it and willing to watch all these games with her. They both crack and pop their knees and fingers together *completely annoying* and tag team me in the kitchen because they both have these food hang ups like hating mushrooms, feta cheese, olives etc (which I happen to like ALL of those). It's like pulling this whole "My Mini Me" act suddenly.....if I say something he seems to question it....BUT if SD says something he automatically takes her word for it. I've also noticed he seems to get sensitive and quickly irritated with me all of a sudden, almost like he snaps or argues about everything I say, even the most innocent of things.

To top it off SD19 is no angel by any means either. Two days after moving in with us she revealed that she had to pay a few hundred dollars for a Drug & Alcohol Driving Awareness Course because she got pulled over with her friends in TX and the cops found weed in the car! SD also confessed to DH that she had smoked pot for years (which we had no idea about) but claims she doesn't do it anymore (yeah right!!). She's also getting all of these letters from an inmate in prison sent to our home. She caimed she went to High School with him and that he was in prison because he got pulled over and the cops found weed (we suspected it was a lie from the start because it made no sense). I googled his name yesterday when I read it on the envelope in the mail. SHE LIED. COMPLETELY. He's 25 so there is no way she went to high school with him. He was arrested for vandalism, domestic violence, theft, drug possession, plus selling, dealing AND manufacturing drugs!! She's into hookah, pot,certain kinds of rap music, a bunch of stuff that's a little too edgy and inappropriate for my tastes. Things that pretty much can be parents worst nightmares and she has a horrible habit of playing Xbox live and turning the volume up extremely loud, where we can hear her little Halo 4 tyrades through the house. Doesn't work....isn't going to school yet.

What really peeves me off is the fact she disappears during the day. Hides in her room playing xbox or whatever she does, totally ignores me and won't socialize BUT suddenly come 5:45pm when she knows her Dad will be home soon she gets the urge to shoot basketball in the driveway so Daddy sees her first thing when he pulls up!! Only then will she come out of her room, has dinner with us and watches TV like it's perfectly normal.

This is starting to drive me crazy, there is more but that's it in general. Is there anyone who has experienced this??
