In fact, act as if you are excited to be going out. If she asks questions about where you're going, and who you are going with (and she will)..........be vague in your answers. I'm not telling you to lie, I'm suggesting you be a little mysterious and don't give her details.
Like this:
H:"W, I am headed out. There is fried chicken in the fridge." Start walking out W:"Where are you going?" H:"Meeting some friends" Keep walking. W:"Who?" H:"You don't know them"
