My mom, 86 had a long time boyfriend who was overbearing, controlling, and sexually active when her mind WAS NOT!
There was no marriage between them, no ownership, no financial community property or funds. Being they stayed together often did not make a marriage so I stepped in, explained NO SEX, no overnights, etc. She is no longer that woman she was 12 years ago.
I changed the locks to her house, called the law, and any invasion of their property is now CRIMINAL TRESPASSING!
Additionally I filed a DO NOT CONTACT with local law enforcement.
Disconnected her phone to his calls.
I'm set and good to go!
She rarely asks about him as out of sight is out of mind & he KNOWS I’ll press charges!
