AITA for wanting to call disability to anonymously report that he’s been lying to get it and that they need to review his case because of this?

Backstory I (27f) and my boyfriend (29m) have know each other for 2 years and have been dating for a year. We moved in together 2 months after we started dating (we had know each other for over a year at that point). We lived in a camper on his family’s property and his aunt, uncle and dad lived in the main house on the property.

Fast forward…. his dad started moving my stuff around, storage boxes I had tucked under the camper, taking stuff and me later finding it in the house (I took it back and got accused of stealing it) then we got into disagreements because he was always volunteering my boyfriend to do things on weekends to the point we couldn’t do things together and we couldn’t even go do our laundry (we did our laundry at the laundromat because he is a diesel mechanic so we didn’t want those dirty clothes washed in his family’s washer in the main house so we just decided to do all the laundry at the laundromat), the response to my message where I stated several times that we didn’t mind helping family and doing things that we actually loved it, but we also have things we need to do and if we could get those things done first we definitely don’t mind helping people was that I was basically saying fuck family.

Well fast forward 5 months (8months ago) and I’m getting told I need to vacate their property that he couldn’t move the camper (he was making payments to purchase it from his aunt and uncle), so I moved in with my cousin and her boyfriend and we are still dating to this day, he stays with me some nights and we always see each other atleast once a day.

Well fast forward to now….. my boyfriend got an accident on Sunday that totaled his vehicle because he fell asleep at the wheel coming back from helping his either wife’s family (yes his dad volunteered him to go help). He is chronically tired from the laborous work he does as a diesel mechanic during the week that he really would like to just sleep on the weekends, but yet his dad always volunteers him to do these things and he feels bad if he doesn’t do those things so he goes and does them…. Today he was on the way home from work and I followed him home because he said he was tired and I was afraid he was going to get in another accident if he fell asleep at the wheel again, his dad was in the yard, but did not see me behind him when he was turning into the driveway or he didn’t notice it was me. But my boyfriend told me tonight that his dad asked him if he was still talking to me or seeing me and when he didn’t respond to his dad, his dad ended up telling him that he was going to punch him in the face if he found out that he was having anything to do with me anymore….

My blood is boiling and I stg if he lays a finger on my boyfriend he won’t like me and the world will know what kind of person he is.

(Yes I know my boyfriend needs to stick up for himself in this situation but he won’t, he lost his mom at 14 to drugs and alcohol and he regrets all the times that he was upset with his mom and didn’t spend time with her, so he doesn’t want to have a falling out with his dad and not be able to spend time with him and not have him in his life… To me, his dad is an asshole and obviously has low emotional intelligence)

But back to my question… AITA for wanting to be his KARMA for being an ass hole and report him for lying to the disability people to get money? Should I even do it or should I just leave it alone? Will it get me bad karma?
