Forum:I declared my child a nemesis? Can we ever become friends again?

In Sims 3, I got flirty with a neighbor while my wife was at work. My toddler was upstairs in his room, but he apparently knew somehow and strongly disliked me ever since then. No matter what I did he still disliked me after that, even after he aged up to a child. I eventually lost my patience and declared him a nemesis. I'm regretting that now, and was wondering if a relationship can be salvaged once it's at that point. I've been really nice to him ever since then, but our relationship isn't improving. So now I'm living with an enemy, which affects both our moods when we're around each other! Any advice?
