I've been with my partner for almost 2 years, and together we have a beautiful almost year old daughter. We also have my two kids full time, and we have his two kids every four days. This past weekend I feel like i'm ready to pack it in. I'm tired of his 12 year old son either ignoring me or getting mad at me when I ask him to do something, or even when I try to explain how to do something. When I talked to my partner about this he just says it's me. And instead of trying to deal with the problem as it happens, he waits until either later that night, almost as if he puts enough time aside, the problem will go away. I love my partner so much, but I'm starting to think I may not be cut out to be a step parent.
