Does the silent treatment actually work?

I have a friend thats always mad at me about something. I just dont respond back. I dont think it has anything to do with me. He's just mad everyone else has excelled in life by 36, and he's still living like he's in high school. It's fine by me, but dont take out your crappy living situation on me. 4 months will go back and he'll be like so are we gonna hang out? I think the same thing eould work on a female if I ever tried. Most of them seem to break up through text these days. Looking back I bet a few would have come back around if I didn't even respond back to their text.
