That's basically it. I didn't even know what to tell him. They don't even have chemistry, they haven't even kissed and secretly he's had another girl on the side for 10 months thats "young and hot", whilst this one that's actually his own age is supposed to be the one he has kids with. He's older than me so on the phone he's doing the whole patronising older brother thing whilst I'm trying to tell him that people much older than me would agree this is a fucking terrible idea, his wife (they aren't married yet but if he has kids with her they probably will end up married) will hate him, the girl he's seeing on the side already hates him and she doesn't even know what's going on (maybe she already does? maybe she knows unconsciously), his kids are definitely gonna hate him even if he "loves them unconditionally" as he says he will... It's all just reading like one gigantic facepalm.

He tells me all this bullshit yet I dared him to bring this up to people older or his own age, or to people that were cavalier when they decided to have kids. I'm trying to tell this guy "your carelessness is going to bite you in the ass, man."

I don't even know what to think anymore.

I just. I love this guy but he's turning out to be a f***ing imbecile... What do I do?
