My DS has called her his best friend since he was 3 and he still does it now. He has loads of friends at school but still says this about her.
Sounds like they have had a chat "i am not your mum and never will be. But I will be your best friend"
When she was pregnant she wouldn’t let anyone visit her daughter until my son had visited.
Sounds like she wanted him to feel special and not pushed aside
He goes to drama club every Thursday and he will only let her take him. He says it’s their special thing, it’s so weird for them to have a special thing she’s not his parent.
he does not remember a time when she was not around. I'm not my goddaughter parent but we have our thing. I also have a thjng with my nephew. Just an aunty thing
He will sit and cuddle her.
Unless there is more to it, sounds normal. She has known him for almost 70% of his life and he does not remember when she hasn't dated his dad
He says he loves her and she loves him. So weird in my opinion.
Again, he has known her almost as long he has known you and his dad
He says she’s his family, she isn’t she just married his dad.
to him, she isn't just dads wife. That is very common when a step parent is involved and been around since you've been a toddler
She has always read him a book before bed. He says she’s the best reader. Why doesn’t his dad do this, why is this woman putting my son to bed?
that you nees to ask your ex. But if she enjoys doing bedtime and he does not. There really isn't an incentive for him to stop her.
He calls her parents nana and grandad and spends a lot of time with him. They take him places like play area and indoor play. They’re not his grandparents. Why is dad allowing this?
Again, you need to ask your ex. You can also try to forbid your son from seeing them. But I am not sure why it is a bad thing that they are refusing to treat the step child differently.
Sounds like you are jealous. That is understandable. But having loving step parent is a good thing. If it crosses a line then it is worth having a convo but nothing seems to cross boundaries based on what you have written. And the reason your son likes her so much is because she isn't his mum. You have different relationships. You know how you can talk to aunt or sister or frienda parent about stuff cause they are not your mum? That is what is happening here.
