I hate my wife and step daughter

I thought I loved this woman so I Mattie her and after 14 years of raising her daughter and being “dad” I just can’t take any more.
Context: I raised my step daughter as just a daughter. We had so much fun and my “now” wife and I really seemed compatible but as of late my daughter (again step) has started running away with so mich consistency that I’ve started to resent her. My wife blames me and im sure we both have parts to play but since I get the brunt of the blame I am so over it. I am the bread winner. We agreed I would work while she stayed at home and raised HER daughter. I have provided a nice house and worked my ass off to make aure things were paid so she could raise our daughter. I am finding as my step daughter runs away repeatedly that I find her less and less to be actual family and more of just someone related to my wife. This was amplified and complicated vy the fact that after 13 years of marriage we suddenly found out at 6 months we were expecting a new child. I now have a “blood” child and I do love her more than ANYTHING. I feel guilty for loving her so much but she has not caused me as much grief as my step daughter. I want a divorce and to kick them both to the curb but I also just want peace in my home, and my step daughter to pull her head out of her ass. She claims she was raped, which could be true so I understand she is traumatized but she also snuck out when it happened and if she had stayed home and been safe she wouldn’t have ever had the trauma so I blame her. Fuck it. I do blame her.
She causes me so much stress I can’t stand her and I resent that my wife chooses her over me. Fuck them both then! I wish they would leave and I could have my baby to raise and live a good life without them. Oh well…..I have tonsigfer in silence and wait for my drug addict teenager who runs away ever .0005 seconds to turn 19 so I can tell get to pound sand and move on with her life…..but at the same time I love her so much and it hurts how much she is hurt8ng and I just want her to pull her head out of her ass and grow the fuck up. I don’t know what to do but my wife blames me and I sooooooooo fed up with being the problem when all I do is provide so she can sit on her far ass and live her mother ducking life. Fu k both of them!
