Apologies in advance, this is a long one. I’ve been with my partner 18 months, we’ve been living together for 4 months with my DDs 21 lives with me full time and 17 DD half with her dad half with me. Dad and I are very friendly exes, no issues there. My DD 21 has never been the biggest fan of my partner, they have very different opinions on politics, global warming, things like that but have always got on ok. DD 17 and partner get on great despite differing opinions. DD has recently bought a house and asked me on Thursday to take her sofa shopping on Saturday, I already had plans with partner and his family, DD 17 was at her dads so I said no. She seemed fine with that but on Sunday my 17 DD told me she’d said I was putting my partners needs before theirs and that he is a piece of s**t. Partner heard this and is upset that she’s said this. DD states this was a rant when she was angry and she didn’t mean it which I understand but I also understand partners anger at this when he’s tried so hard to build a relationship with her. He’s now saying he’s done with her and having any kind of relationship. I’m so stuck in the middle, I see both sides but I just don’t know what to do. I cannot continue in a relationship with someone where my daughter is not welcome in my home, my mother did this to me and it was deeply damaging but I also love my partner to death, we had a miscarriage in May and are next to be getting married and trying again for a baby. I just don’t know what to do- does anyone have any advice?
