I have my own 2 children 15 and 12 and 2 step daughters 12 and 14, the oldest step daughter I get on fine with and I'm close to my own 2. The youngest one is so bloody rude to me, tells me she hates me says things like I don't have to be nice to you you're not blood! Your just someone my dad dates I don't know why. This morning she refused to come in holiday as she hates me. I've tried talking to her, my dp has talked to her over and over again, told her off we've all sat down tried to reassure her ask her what's wrong, how can I make her happier, but I just get the shoulder shrug! I really can't take much more of this and debating if I should call the wedding off , I'm sick of it and it just doesn't change.
