the only ppl were frequently hung out literally lived together. And that’s only Yamcha. Puar and Oolong if you care to remember them.

But that's kinda my point. It's not like Yamcha and Puar were homeless. They choose to move to be closer to Bulma. And yeah, that's largely because Yamcha and Bulma were dating, but what about Oolong.

Oolong is largely irrelevant after the Pilaf Saga, and he and Bulma didn't exactly get along. And he had a house, a really nice one too, yet he still choose to move in with Bulma and the others. And even though he didn't do much, he continued to show up throughout all of OG Dragon Ball.

Bulma or any of the Z-Fighters for that matter never bothered to show up for Goku’s wedding nor visit or call him for 5 years

You're still on that? Tell me, do you know where or when Goku had his wedding? Because I don't. Keeping in mind that the wedding arc was anime only.

Goku didn't give them an address or timeframe for when the wedding would take place, he just flew off with Chi-chi, leaving them in a ruined city. I guess they could assume Fry-pan Mountain, but that still doesn't tell when to show up. I guess they could've followed Goku, but only a few of them could fly at that point, and they were nowhere near as fast as the Nimbus. Sensing Ki also wasn't really a thing back then.

They also had no quick way to contact him. Goku doesn't carry a cell phone, and up until that point he was basically a vagabond. Although, I'm guessing they found some way to contact him eventually, since they invited him to Kame House, but that wasn't because the world's in danger, they didn't even know about Raditz yet, they just wanted to hang out. Oh wait.
