I do not know where to start or what to really say so I don't sound petty... I feel like I'm in a battle for my spot as the gf and soon to be wife. SD is 3..  Like I have to battle for attention with sd3.  My soon to be sd3 is use to having him to herself.. She is spoiled rotten and he basically caters to her every sound.  I have 3 of my own and they know their role as kids but SD thinks she is the boss.  The queen of house.  If I tell all 4 no she goes to him and whines to male him feel bad. She refuses to eat what I make for dinner.. I make the 3 that are my bio kids eat what I make.
