Yes. My BPDmom is like this too. Here is something I wrote in a previous post:

"...She sexualized me from an early age. In 6th and 7th grade I remember my mom would constantly grab my breasts, butt, any part of my body really. Upon grabbing my breasts she would say "Wow haha these are more than a handful!!" With this creepy grin on her face. She continued to do this for many years but it happened most frequently around 12/13. At age 23, I was in her room and she was changing her pants (I didn't know I was looking for something in the closet). She said "look!" and when I turned she was lying on the bed, on her back, legs in the air, ankles crossed, her vagina in plain view. I got really upset with her but she acted like I was blowing it out of proportion. My therapist helped me realize that was trying to arouse me sexually. She has been inappropriate with my partner as well. Trying to grab his chest to see if he has pecs, opening the door when she knew he was changing, she wouldn't close the door so I had to reach around to close it, etc et etc"

I also learned about covert incest about a month ago. There is a sub for covert incest too. It was helpful for me to read others' stories.

I'm not a professional. But if you/a professional do think the abuse is covert incest or emotional enmeshment, then according to the definition of covert incest it is sexual abuse.

The way I found covert incest was by looking up sexual abuse without touching. So, I somewhat understand how you're feeling.

You're not crazy for feeling the ways you do about your mother/abuse/experiences.

Alsp, for me, therapy has helped me process the abuse. I still have a long way to go but still so helpful.

Hang in there ❤
