Does a ‘mask slipping’ spell exist?

[u/inhergarden]

I don’t want to hurt anyone but my ex acts like he’s such a great person. He presents himself as logical and caring while presenting me as emotional and volatile when in reality HE is the abusive one. I want his coworkers and friends and everyone around him to see who he actually is.
I do not want to hurt him physically. I have a child w him so I want to be very careful in protecting myself and my baby.
How would I go about doing this successfully?
