Tough.

I love my fiancee, but I'm starting to dislike her daughter...

Let me preface.

Newly engaged. She has a 10y/o daughter with ASD, learning disabilities, ADHD, other medical issues. She absolutely runs our relationship. "Mommy I want this!"She gets it. "mommy Im …. this, that and the other” to get my fiancee’s attention. And it works Im so tired. I dont know if I can deal. I love my fiancee. When we are alone it is bliss. When her daughter is here (she lives with us and her dad isn't in the picture). I genuinely hate it. She is not in any therapy or OT or anything. She hides behind the sentence "I'm overstimulated!" when anyone tells her anything. She treats her mom like shit, treats me like shit. I feel like I'm secondary in this relationship.. like a third wheel. Ive tried to make a relationship with daughter. It just doesn't work... Her daughter hates me, and Im starting to dislike her back. I'm 23... I always wanted kids of my own. I don't know about that anymore.

Im at a loss in what to do...
