Call me crazy....
you want them to go. You want HIM to go. You want your child to go. You want everyone to get along. Your child is like an older child and having trouble adjusting.
Ask her to come with the kids and stay at the same resort.
She won't have the guilt of not taking them herself. She might opt out, but know that you guys are serious about going together. She might come, have her kids part of the time, and have a nice rest the rest of the time.
Book the vacation for all of you and make sure it is refundable. You can add/delete people as you want, and even cancel if it doesn't work out.
Don't tell the kids.
Unless they don't get along at all, it might be a great compromise.
My man never gets to see his kids. They live in another province. Their mom is certified..... well, I've met her a few times and weird, weird history. His sons were finally supposed to come and visit for a fathers day weekend. She cancelled 2 days before after months of planning and him being delighted and full of joy. His heart was broken. Then she moved again and he can only communicate with his sons (who are older) through Facebook.
Compromise, h-e-double hockey sticks, offer to PAY for her to go. You don't want to see the look on his face. If it doesn't work out, you will have some peace knowing you did everything you could to make it happen. And don't talk to her yourself in any way about this, it is his business. Trust me, interfering step parents make for a bad childhood (my parents divorced when I was 12, and it was a 6 way battle for me for the next 6 years - step parent, dad, mom, grandma A, mom's random boyfriends, me...) - tread lightly, and the best of luck that you can make it work for all of your happiness!
Ok I am not officially a step-parent yet but soon to be. My fiance and I want to take his three kids and my one to WDW in Novermber over Thanksgiving week. This way they would only miss 2 days of school.
Their mom has primary custody so he ask her if she would allow them to go as this is her year to have the kids Thanksgiving day. For the past several years she has worked on Thanksgiving and the dad has had them anyways. The first thing she told him was, "They cannot go without you going." Well DUH I was not planning on taking four kids ages 12, 10, 10, 8 to WDW by myself. We planned to go as a family as we should be married by that time.
She never did give him a definite answer and he says he will not feel right going without his kids. He nor his kids have ever been. I know he will go if I insist but I do understand why he would not feel comfortable going. Should I encourage him to go anyways?
So do we plan the trip and hope that she gives us permission? Do we just cancel it and disappoint my child? My fiance said he did not mind if we go even if him and his kids do not get to go. I think the mom will let them go but who knows. I know if my son's dad wanted to take him I would be happy for him to go but me and my ex have a good relationship. Fiance and his ex do not talk unless absolutely necessary.
The only other option would be to go next summer and it is just too busy and too hot then.
I am knew to this step-parent stuff so any advise or help you can offer would be welcomed.
