Although I don't know if I should still call you that, given the actual situation of the family, which is all your fault. Thanks to you and that bit Miss Bell our family is broken! Zara and Tony are with you and me and Ian are with Mum; I rarely spoke to my sister before, but I'm sure we'll never speak to each other again! And it's all because of what you did! How could you do that to Mother?! She was your wife, you had a family with her and yet you created another family with another woman! You knew of his existence all this time and you never said a word! How could you?! Mum must feel so humiliated; we all do! I don't even know what to say to Ian! He's too young to be going through all this. Didn't you stop to think about him? About all your (legitimate) children and how it would affect us?
Just know that after this letter I am never speaking to you again.
