Step kids. ...

Am I a horrible person because I don't like my step kids? I dread when I know they are coming. I get all stressed out. My nerves are shot. I just found out I'm pregnant and I don't even want to think about my kid acting like them or them touching my baby when it's born. Their father acts different when they are around. Towards me and towards my children. I've tried for 2 years to find a connection and I can't. I don't want to try anymore. If I never had to see them again I'd be perfectly fine with that. I feel horrible about it but it's true. Ugh. I am a horrible person.
