After reading NMMNG and parts of the sidebar (so much information)... Should I inform and warn my friends who are in a relationship or about to be in one to be cautious, or should I just shut the fuck up and let them wake up for themselves.

Here are some context:

I have one of my best friend who have dated this girl for about 4 years. They always argue, she's always asking for 2 weeks breaks randomly, and is very rude to him around other people. But he loves this girl to death, because he thinks that she's a solid 10 who has a master and a well paying job. To him he thinks he found a unicorn to marry.

Another one of my friend is talking to a single mother of four kids during the Quarantine. He constantly texts her to the point when we're watching a movie or playing video games he has to pause it to text her the moment he gets the notification. They're co-workers and she visit him from time to time.

Lastly, my other bro is talking to his girlfriend 30 miles away through FaceTime. I would say he's very happy when she calls him to talk over the phone. She posted my friend on Facebook to show them off and they seem to be very compatible (from what I see and hear). He tells me that he found his unicorn and will marry her and start a family. *Mind you we're in our mid 20s.

I would love to share with them the red pill. But because of my white knight simpin background they assume I'm unqualified to give any relationship advice to them at all. (They always pick on me for not getting laid or being single all my life). I want to help but don't want them to think I'm jealous. I just want to wake them up like I have.
