Hello, I posted this on AIBU - but thought this might be more appropriate.
I separated from my children's father 2.5 years ago, and 6 months ago, his new partner (I will refer to her as 'A') and her two children moved into what was our home. Her youngest child ('B') has joined our children's school.
I am struggling with my feelings around this.
My children say many negative things, eg.
"I never get time with just Dad because now 6 people live in our house",
"I never get space from B because she is in my class and at Dad's,
'A lets me sit in the front seat with no car seat and listen to songs with the F word',
'B says naughty words all the time and Dad smacks her',
'A doesn't make me wear a helmet',
'A vapes but she told us it is a whistle', etc.
Our 6-year-old son has phoned me and sent messages while with his father saying A's teenage son is being mean to him.
But they also say positive things, about the presents A buys them, and are excited about all going on holiday together. A frequently posts photos of my children on social media which portray happy times. My children talk with ease about their step-mum and step-siblings.
For reference, her children have different fathers and have had a range of living situations in their lives, so the vocabulary of 'step' is very normal for them and I think my children have picked up on this, not necessarily giving it the weight I do.
Their father and I are very different in terms of our perspectives on parenting. I don't feel I am in a position to talk to them about anything - and what would I say anyway? - because of this difference in views - the lack of helmets, car seats, swearing in front of children, smacking them, etc, are all things he condones (and part of the reason we didn't work!)
We went through court to arrange custody, being unable to come to an agreement together, and none of these things matter in the court system here (nor does his drug use or refusal to stay under the legal driving limit when he has care of the children). I have worked hard to try and accept this - that what I thought was clear-cut 'wrong' behavior is actually not in the eyes of the law.
I have tried to be supportive of this change for my children, and have for example, bought her daughter a birthday present from my children (there was no thank you from either A or my ex), and have also had B stay the night with my children when my ex and A needed a babysitter.
I have a new partner who is amazing and are in no rush to move in together because I don't want my children to be juggling this step situation in both of their homes. I like that my time with them is undiluted.
Even as I write this, I can feel a clear bias towards this woman and I don't really know her to be able to judge. She doesn't talk to me (even when she dropped her daughter off to stay the night, all she said was "A has a bit of a cold"). Avoiding each other at school pick-ups and drop-offs seems to be an unspoken strategy.
I guess I am not asking if I am being unreasonable but for any connections/wisdom in regard to all of this. How can I be less biased towards this? I don't want my children to feel divided and worry they pick up on my feelings, despite my actions.
