Not really an aibu but has anyone not had a big falling out with a friend as there is too much drama?

I think my friendship is toxic. She undermines my success, seems happy when I experience misfortune and has been out with 2 of my exes. Bluegh!
To top it off she is a massive huff as my dd dosn't want to know her dd ( after something mean was said.) Dd has been used as a bit of a scape goat for her dds woes ( because my dd quite rightly won't play with her.)
Trouble is her mum and my dad have been going out for ages ( dad started dating her 5 months after my mum died.)
Overall, it's a bit toxic so am I right to let things drift rather than have a big fall out? I just get the feeling we don't really like each other anyway.

Just let it drift. That way, it won’t be awkward at any family functions because you can both pretend you still like each other for an hour or so, but you don’t have to put up with her nonsense. It’s certainly not worth having a big fall out over. That just adds to the drama and she’d quite possibly enjoy it.
