I say you sleep with a knife under your pillow, or he's just pulling your leg... I hope.

Dump him and runnn!

Well you never know maybe his mom was abusive but he didnt want to tell anyone so one day he just snapped but didnt tell thebpolice his mom was abusive....its a bit far fetched but still

Get away while you can!!!

Ok heres what you do, fake your death, and run far far far far far far away, and when you think your far enough, go further.

Buy a gun

That doesn't mean he will do anything. he was having issues in his past and then received help for it. like, for example, I was diagnosed with ptsd and a severe anxiety disorder from being badly abused as a child, she's that mean that I'm an angry person that will do the same to my daughter? just because someone had issues in the past dies not mean that they remain. he was deemed sane by the professionals so unless he starts to prove otherwise to you, don't freak out and over complicate the situation.

Wow. Kinda scary. But give him a try. It might have been that he'd snapped or something. Mental breakdown. Just keep an eye out for warning signs.

Now who of us haven't wanted to kill our mother for something or other. He actually tried to go through with it. He is a real go getter.

It's possible that maybe his mother was abusive or something, and he had reason to kill her
