MIL attacked me..

So two nights ago was my bf birthday. He went to the bar with his mom & had a few drinks.. i was pretty pissed because i wanted to spend the night with him for his birthday & he ended up spending it at the bar.. he comes back home & brings me roses i get into an argument because it was suppose to be our night & tell him i don’t want the roses... anyways, he goes back to the bar & there’s a woman there that his mom had previous issues with. She’s 40 years old by the way, long story short they get into a bar fight she takes off her heel and slashes the girls eyebrow bone open & my bf gets arrested. She comes home (it’s her house) barges in the room & starts yelling at me calling me a bitch in Spanish saying it’s my fault her son got arrested! MY FAULT?? she said if i didn’t fight with him beforehand he wouldn’t of fought someone at the bar SHE had problems with. He gets out of jail & comes home and she’s talking shit about me. I tell her to shut up it’s 2am & your screaming and stop talking about me & she SCREAMS SHUT UP!! I said you look crazy she says again SHUT UPPP!! Comes up to me & pulls my hair. My bf got in the middle & i looked at him and told him get ur mom off me... a few seconds go by and my head starts tilting so i grab her hair & she starts clawing my eye down my face to my chest... and rips a chunk of hair out. She gets arrested & she has the nerve to be crying i pressed charges and now she won’t be able to work the medical field & she sat in jail the whole night... LIKE HOW ABOUT YOUR FUCKING SORRY?? she clawed me like she was truly trying to seriously hurt me.. Thad the worst part about it... she was really violent. I was thinking about going to the place she’s getting schooling done to get her CNA and showing them these pictures..? Should i?
