I don't really know if I'm looking for advice or just needing to vent, because I feel like I've tried everything.

Me (20F) and my ex (22F) have known each other for more than 6 years, but we dated for 2. We broke up quite a while ago and have taken the time to heal and resume our regularly scheduled programming as best friends. She is absolutely my soulmate. 

However, she irritates me a lot. I always confront her when there is an issue, but at this point, I don't know why I should. The problems don't go away-- they just keep persisting, despite my efforts. 

She lives in an extremely abusive household and is extremely dependent on her parents, which is what has been preventing us from making any real progress, in my opinion? 

Because of that, I've decided against communicating my feelings to her. I know she doesn't have bad intentions, but she made a jab at my autism the other day and I just acted like it didn't hurt and kept my mouth shut, even though she was blatantly wrong.

I don't know what else to do until she is able to get away from her toxic family. I think she needs treatment, but no matter what I suggest, she always has a reason as to why she can't access it.
