It's hard for me to fault this person, cause he is ill. But if you know anything or can get involved, You have to do it. Do it because you care about your friend. You also can call that mental health line if you want some advice about how to proceed. If this was someone close to me, I'd feel awful if I didn't do everything I could before this gets even more Serious.
I'm sorry dude, But your threatening a woman. This is out of control.
These are the things, in this society, that get me down, Some guy out there thinks this stuff is "funny" or "amusing" or "A Joke", and it's a Rationalization to terrorize a woman. I'll bet money that there is some friend of his, who knows about it, and is ok with it. Or dismisses it as just some of his "Eccentric" behavior. This is escalating Kids!!
If you don't know what to do, or are confused:
They can help you, or help you to intervene before this gets even more out of hand.
Say, "Hi My buddy keeps tormenting this woman, and I'm afraid it's turning dangerous. What do I do"
"I'm really having some troubles, and I need to find a mental health professional to help me."
Get Him Help!!!
This has become Criminal and dangerous!!!
I'm doing everything I can? Are You?
Dude!!!!!! Get Help.... Please!!!!!
You're not Well!!!!
