Does it get better?

My stepkids mom is extremely high conflict and extremely neglectful. She struggles with some kind of personality disorder where she has manic and depressive episodes in which she becomes very hard to deal with, especially the paranoia. I’ve honestly been wondering if she’s struggling with addiction as well. She’s also pretty neglectful and overall doesn’t seem to enjoy or want to be a parent. She herself has stated she never wanted to be a parent, she uses the child like an accessory. I can get over a lot of the bs just not the blatant neglect. It’s just not something I can be okay with even if you’re struggling with mental health issues. She has plenty of ppl offering help in a magnitude of ways, she’s just too prideful to accept it even tho it’s impacting her and her kids negatively. Since I’m the type that speaks up and holds boundaries I am hated and my stepkid is often punished for it. Sometimes I wonder if I’m just making things worse. It’s been two years of bullshit since him and I got more serious. Different types of threats, matted hair, being sent in soiled clothes, filthy clothes that don’t fit ( literally every size from 6months to women’s large), bug infestations at her place, cps investigations, concerning choices like having her young child room with an 18 yr old girl she wasn’t related to and they only knew for a year, major skill regressions including toileting, nightmares and night terrors, and the list just goes on and on. Literally in the beginning she’d cuss us out for asking her to send the child in shoes… during wintertime in the north. Before she learned we were getting serious she would only see the child for a few hours a week and often times would be hours late or no show. Since I’ve been in the picture to this day, she has only bought a handful of clothes for the child and 2 pairs of shoes. She fights him on everything and thinks since she’s the mom she has all legal rights to do so which isn’t true. She vetoed therapy even though there were insane enough red flags that cps got involved, she went behind his back and chose a different school because she didn’t want to provide transportation ( she wanted her to just get on the bus), and she changed all the kids doctors and medical insurance then refused to give him any info about who her dr dentist or insurance provider was for a whole yr. He’s been saving for the last two years and finally has enough for a lawyer but honestly my hopes r low even with the evidence we have.
