basically my mum has gone a bit crazy and has split up with my DSD (darling step dad) to go out with someone she was with years ago. personally i think she's having some sort of mid life crisis because i do not trust this man as far as i could throw him. he fills her head with all sorts of rubbish, which she believes to be god's word and has now talked her into selling our house and buying another one and also apparently they have plans to get married. i was worried he would then divorce some time letter and ask for half the house. when i spoke to him about this he said he was willing to sign a clause or something that said if they got divorced he would not be able to ask for half of the house. is he talkin rubbish or does such a thing exist? i always thought things like prenups meant nothing in england?
