I’m sure Seb can think for himself but is it really beyond the realms of possibility that his thoughts and feelings and opinions are influenced by the adults he spends time with? Who are all related to his dad and his stepmum. There is apparently 0% input from the other side of his family.
And what about Isaac? We’ve heard a lot that Seb made his own decisions and didn’t want to see his mum but Isaac is only 10 now, how old was he when this happened?
I think my point is, from what we see daily of Rachel’s behaviour and attitude, I cannot believe that those boys ever get sat down by Josh and/or Rachel and asked how they feel, whether they have any questions etc, and if they did I’m not convinced they would feel comfortable enough to be honest. We’ve seen Rachel’s reaction when Josh leaves the house alone - can you imagine she would entertain the idea of him facilitating contact between “her” boys and his ex wife? I really cannot.
Obviously that’s just my opinion, I don’t know them in real life and maybe the whole social media persona is a massive act and she’s actually a decent person. But I doubt it.
