Tanya was not thinking of the children when she did this, it was all about her, revenge! She, just like many women in real life, even used the children against Max, keeping him from seeing them! She sent him away and allowed the children to think he just upped and left and didn't care about them, and began an affair with his brother for crying out loud which ended later 2008! She was then back with Max on and off for years after, even cheating on Greg, her husband in 2011 with Max! She has issues as much as Max does and finally admitted to it in her final episode in 2013!
Syd is right though, Stacey is fresh out of hospital and vulnerable! Bradley just doesn't wanna acknowledge it, he is just thinking about himself, his own feelings like he always has! He's never actually asked Stacey how she felt, except for when he knew there was something going on between her and Callum, but the signs that she didn't love him like that were there from the beginning, each time they got back together! Stacey got back with him because he loved her, not because she loved him!
Samantha has been on my mind lately too much lately but he just keeps going through my tweets like ❤️ he deserves the credit he has received in his career as an actor in this year so yeah he is definitely one to keep going for a while 🎉
