All right, I wanted to let you all know what happened.
Due to seeing people online and no neverletthem, I decided to host because I was in a good mood today.
The good thing was everyone was listed who was playing online and I had zero issues inviting people.
The bad thing was at one point, Jest311 got disconnected and tried sending me an invite. Because of this, I was not able to select "No", I do not want to accept an invite, and I couldn't back out pressing circle. So basically, I was stuck, so I tried to warn everyone I'll re-create a party. So it takes a REALLY long time to re-direct me. I tried pressing the PS Button to quit, and it froze too so I couldn't even quit the game. Eventually it redirected me, but the screen was dim due to pressing the PS Button, so I had to press the power button on my PS3, which shut it down, then I turned it back on. Since I have a crazy amount of buddies, I had to wait for all their notifications of being online to appear before I could get back online (I had like 18+ buddies online at once).
If it weren't for that, everything else ran smooth. That's why I get so frustrated with CoD4. From now on, if ANYONE gets disconencted from the party, please do NOT send me an invite ever. Send me a PSN message saying "Invite again" or "got disconnected" in the subject line and I'll invite you.
CoD4 still made me upset that I'm considering dumping it from CAG PSN Gaming once this month is over.
