Hurt and Confussed

[oad]

I have a quick question....tomorrow my W returns from her trip to vegas, she gets to the house around 11 pm. Im staying at the house and when she returns im leaving back to my dads place. Should I ask how her trip was or just say hi and that im tired and leave? Im following what sandi2 suggested which was be indifferent. today there was no contact so far.
