WIBTA for ruining my exs life and her families after she ruined mine.
For context. I 20M and my ex 21F jackie (not name) lived together for a while. I found out that she cheated on me and stole 500 a month to use on gambling.
After we broke up, jackie ended up moving to her mothers. She is wants me to pay her bills and everything because I promised her that if we broke up that I'd do that. Jackie never wanted a job so I gave her the option to be a housewife.
How she ruined my life: I am currently unable to afford rent due to her constantly making absolutely psychopathic threats while I was at work. I had to keep going out of work due to her being a psychopath and saying stuff like "I'm going to burn your home if you do not come back by X" or "If I catch your dog, I'll kill it."
How I could ruin her life: Jackie's mother is getting government help and Jackie is claiming the same benefits but under my address since she's legally a Tennant. If I remove her from the tenancy agreement then she'll have to change her address to her mother's which will make them unable to pay for necessities. Also I could mess her life up by taking back everything I lent to her such as a PC that is being used by the whole family to study, complete homework or Jackie playing with the dude she cheated on me with.
WIBTA if I messed her life up for her psychotic behaviour?
