Background to this is that I have been a LP for 12 years and have 2 DD aged 23 and 20. The older one has left home and the younger is going to university at the end of September. I have been dating BF for 15 months and he has no children. We have broken up a couple of times and I have been really upset. Since then, he has been helping me with jobs around the house, decorating and DIY. The result of this is that youngest DD has been rude and hostile to BF and he now says that no-one has ever been so rude to him in his life and he will never speak to her again. I have said that this makes our relationship untenable.
I think that DD is both protective of me and that the timing is wrong for her as we have always been close and I am developing a new relationship at a time when she is leaving home.
Am I being selfish? I do not want to lose him or to risk my relationship with her.
