I think you are being unreasonable, but I mean that with understanding, because it is SUCH a hard situation to extricate yourself from. I have been there. I have been consumed by the bitterness. It's no way to live, giving her all that power over your reactions and feelings.
I think it's for your benefit if you withdraw from her. You don't owe her anything. You can't change her. So put yourself first, always. Either suddenly or gradually, whichever works best, hopefully with therapy or something to help you along the way. Don't tell her stuff, if it backfires later. Don't arrange to see her if you don't want to. Don't give her room in your adult life to opine on anything. Amd it works both ways, don't judge her. Don't presume that it has to be so black and white. She is who she is.
Sometimes to save ourselves we have to really cut things back to the bone and only surround ourselves with situations that aren't damaging us. Your struggles and achievements aren't worthless, just because she's done it differently. You're not her, so what is to be gained from comparison? Even if you know her inside and out put, you can never truly know her reasons for any choice she's made.
And actually, there's nothing wrong with what she's done with her life either, we are all different, it really doesn't matter how she spends her own time. She's allowed to do what you view as nothing. Maybe that's all she can cope with. It doesn't matter, the whys. You're an adult now but it's still painful, and somehow still seen as weird in society to distance from a mum, even if they are toxic. So you must prepare yourself for that if you want less of her on your life.
But if you know for sure she just cannot be what you need, you can also make a choice not to be stuck, as you seem to want her to make that same choice... Set yourself free.
