Saying "You should kill yourself" - Is it ever forgivable?

Theoretically they are forgivable. But there is no right to forgiveness. Especially uncontrolled anger can make people really lonely and isolated real fast.

I would recommend getting yourself into therapy. Chances are that if you're anger is of such dimensions that there are other issues in addition. Please do this and ask the therapist to explain to you how you can mend this. One can also go and ask for better ways dealing with the whole situation, it seems as if a big part of the frustration is that you feel helpless in the face of his behavior and problems.

As for the boy, he would probably benefit from therapy,too. But you cannot make him go, you can only work on yourself.

As for calling his bluff etc, this can backfire. People don't always have healthy ways of expressing themselves and being dismissive will only cause more problems in the long run. But you know, it is your girlfriend's job to raise him. What is she doing about him? That's a conversation you should really have, obviously her son is somewhat troubled and not getting the help he needs.I can't believe he woke up like this when he turned 18, considering this blaming makes even less sense. It is simply illusionary to expect someone to be able to handle everything and themselves simply because they are a certain age. If it's lacking in that area then they either have a neurological/medical problem or something went wrong during childhood/adolescence. Think about it and good luck.

I don't understand what the fuss is about. If I were you, I'd return to normal life like nothing happened because nothing did. You were mean to a grown man who threatened you with weapons less than a month ago. He needs to get over it. You're not even his father. I don't get why he'd care at all. I know I wouldn't.

In fact, both of my parents have told me they wish I was never born. My mother probably apologized, but my father never apologizes or admits fault. I most likely made a nasty remark of my own in response, but I didn't lose any sleep over it. They're just words. This "abuse" was so inconsequential to me that I barely remember it. i haven't blocked it out...I just can't remember every little hostile exchange that ever happened in my life. I've had much more memorable feuds with my folks, esp. my dad.

I genuinely think that your actions were normal and so were my father's. His parents did things to him that would make your jaws drop to the floor and it didn't ruin his life or even make him bitter towards his parents.

I have to consider the possibility that my situation is analogous to a North Korean who has no idea how the rest of the world lives. I describe my childhood as fairly idyllic aside from the usual conflicts with my parents and I'm not lying.

People really tend to do or say those things if anger strikes them because a lot of patience has been taken for granted. Maybe I can also do that. Besides, he is also at the right age for those stuffs. He should know where to put himself in. If he just can't realize all of those things then just understand him. Maybe he is having a hard time in some things in his life.

If you are asking for forgiveness, I can say yes. and why not? Just prove to him that you are sorry and also make up to him. let him understand your situation as well.
