So my sister broke up with a guy recently and he turned full psycho. For 2-3 months he kept harassing her by calling her 100 times daily from different numbers which we did not know about. Then suddenly I got a call from the guy and he started threatening me and abusing. He wants to "teach my sister" and our family a lesson. Being red pilled, I am not looking at my sister from rose tinted glasses. He might have flipped with very good reasons.

He gave death threats to our parents who are senior citizens as well. My dad recently informed me this has apparently happened before as well. He got threats from a guy from her past too. This seems like a pattern to me and I want to keep myself and my parents safe. As I understand, my sister loves drama and anything normal is boring for her. This guy has her all her friends phone numbers, whole family's phone numbers, and our home address too. We had to file a police report and investigation is on.

My question is- its very hard to see my little sister from a RedPill lens. But I know the truth. AWALT. But to me it seems like this pattern could have some dangerous outcome for people around her in the future. How do I keep myself and my family safe? I am genuinely worried because I know how women like her can turn life upside down because of their stupidity.

then texts "I'm free that night. I do have a boyfriend but I thoroughly enjoyed our conversations if you're interested in another friend up here."

There was no mention of a boyfriend the entire night. What do you think are the chances this supposed boyfriend actually exists as opposed to her wanting plausible deniability/validation/free drinks?

What @mattyanon said. He most likely exists, but that didn't stop her from using you for free shit. Women use men for free shit all the time. In other news, water is wet.

Where is this boyfriend while she's drinking and flirting with random men on the weekends?

Probably at work.

I don't mean this to sound like red pill rage bait but that is actually what happened.

We've all been through similar.

Check it out: in addition to what matty already said about probing, this is also a good reason to escalate early and escalate fast. One drink, then kiss attempt, and getting "I have a boyfriend" is a lot better than wasting as much time, effort, etc as you did.

I tell him they seem like timewasters looking for free drinks and entertainment... My girl continues to show to be a timewaster

You nailed it. Listen to that voice next time.

but he says "he could see something longer term with his girl".

He hasn't even fucked her yet. That's retarded.

All that said I'm not upset to have a hot young girl to value tap and use as social proof

I doubt she'll be all that useful in that way. Try getting her to set you up with one of her hot friends. See how that goes. If she makes excuses, she's trying to keep you as an orbiter (this isn't necessarily conscious on her part, but rather instinct).
