I'm struggling with a family situation and wondering if anyone can offer any advice. My brother divorced 3 years ago and has since met a new partner with kids. We have a gorgeous nephew who is now 8 and we don't see much of him because my brother doesn't keep in touch with us or make the effort to meet. We have seen our nephew 6 or 7 times in the last 3 years.
My Mum has started to become so sad about the situation (she often cries about it) so I reached out to my brother's ex-wife (nephew's Mum) and asked if we could see them. She was more than happy to bring our nephew to his Nana's house and we were overjoyed to see him.
Since then my brother has kicked off sending abusive messages to my Mum saying she is not allowed to see his ex-wife. He says they are going to court over child maintenance and that we are harming the situation.
My brother has been very controlling since the divorce which is why we lost touch with our nephew's Mum. He said legally we were not allowed contact with her so we cooperated and is now saying we still can't see her because it will affect the court case. As far as I am concerned this is between them and does not involve us.
Are we being unreasonable for wanting to see our nephew more regularly and maintain a positive relationship with his Mum? And by doing so could we be affecting the court case? Legally, I'm assuming we are allowed to see them, but I wanted to know if anyone had experienced a similar situation and if you have any advice. Thanks in advance.
