Help! I'm so hopeless and devastated...

[peaceSJ]

This long weekend he is going to be gone for three days without telling us where he will be. The kids didn't know that and already asked where we'll go on labor day. He's planning to tell them he will work overtime during this long weekend. I disagreed and insisted on not cheating on kids. If they foud out later, they'll be very disappointed. Am I right? I feel so hurtful, but how should I deal with this situation? Should I just let him do whatever he likes and pretend I don't care?
