explain how you and him (kids -if you have) are looking forward to spend some quality time together. holidays are for relax and enjoy not for stress.
Oh no - I can feel your pain. You could tell him (calmly) .. look - you want to go on vacation with them, fine, go - but if you're bringing them along, I'm going on my own vacation - (and be prepared to follow through)... Just recognize ultimately, it is your choice to go or not.
Tell him. Isn't there communication in your marriage?
Just talk to him and try to explain to him in a positive way why you would prefer just the two of you going on vacation, and maybe when you take another vacation you can invite his sister and her family.
Just tell him you were really hoping it could just be you guys so you could spend uninterrupted time together. With lots of crazy weird sex.
Refuse to go with them.<br />
Have a lovely quiet break a home.
For him to understand you will have to put yourself in his shoes. How would he react if you invited your sister and her husband and kids. Come at it from that angle. I would give him the same courtesy or the same "this is the same thing as"
ouch. one of the oldest and hardest problems there is. unfortunately, i have no idea, other than ultimatums. family is tricky.
