Before my cousin took back her cheating debt ridden H her mom told her she'd never speak to her again if she got back together with him. She did it anyways and years later there is my aunt, staying at my cousin's house and all is well.
That's the main reason I told no one when my H left, I know they'd just make things worse and tell me stuff that wouldnt' help.
You have to be very firm and brave, and just come out and tell them that this is your choice, that you are happy and that this is what you want, that you dont' appreciate anyone bad mouthing your H. They might feel insulted, but you aren't 15 anymore and this is your family and it is YOUR life, too bad if they dont' like it, seems they have a strong hold on you.
My father used to be like that with me, still talked me and treated me as if I lived w/him and as if I was 10. He'd get so mad when I contradicted him or I did things that didn't agree with him (I was already married w/1child) Eventually he got it, that I was going to do it my way regardless of what he thought.
It is just horrible that members of your family are saying negative things to your daughter, I don't know old is she but whoever is saying these things shouldn't be around your daughter if this is how they will behave. Can your d see a C perhaps? it's sad she feel this way about her father.
I won't say anything else about the ow and your H, I already said my peace in that regard, though I truly hope that he comes around your way and that all goes well.
