So i need some words of encouragement or advise.

I am a happily married woman of 12 yrs to my husband

We have 2 kids together.

He has a 13yr old daughter from another relationship.

My husband co parents and we have my step daughter Friday-Sunday and on all school vacations.

Step daughter and i have not gotten along in about 2 yrs because her bio mom keeps trash talking me to her. Step daughter tells her dad and we see the text convos in her phone with her mom.

Needless to say I’ve tried everything to be on good terms. I take her shopping, when dad is away for the military I still pick her up when i take my kids places. Bio mom doesn’t like when i take pictures of her and my kids together, or of her and i, and interrogates her once she gets home.

I am beyond over this.

Dad knows how I feel because he too feels the same way.

So we have a vacation coming up and i do not want her to come. Let me explain why.

I recently asked her if she was ok with going she said she’s not sure. We took a day trip 2 hours away from home and she called her mom to complain about everything. I felt to annoyed I just wanted to go home and felt so bad for my kids. And yes every time we do things with her she face times her mom to complain how she much rather be home.

Our trip is 2 weeks long and on the other side of the US.

I REALLY DON’T WANT TO BE AROUND MISERY FOR 2 WEEKS AFTER SPENDING THOUSANDS AND PLANNING THIS TRIP FOR MONTHS.

We do want to go to Disney world for one day and do rides. Not that it matters to me but she is a teenager but is about 260lbs meaning rides will not be taken because of safety reasons so It will be a waste of money.

How do I bring it up that I prefer her not going.

She has gone to Florida with bio mom before and with us 4 yrs ago but I just want this to be a peaceful trip. Am I wrong???
