All that stuff about you not being in the band any more.

Dave: Are you sure you aren’t coming back today, with me?
Amy: No, Dave. I told you – I’m talking to Saints Alive this afternoon.
Dave: Well, OK. Listen, Amy. I’m really sorry – I hadn’t realized how upset you were about Joanne. I’ve been a bit stupid. All that stuff about you not being in the band any more.
Amy: It’s OK, Dave. I think Joanne had already decided before the contest that she wanted my place in the band – and my boyfriend.

All that stuff about you not being in the band any more.
I think this sentence means ‘All that stuff about you will not be in the band any more.’ Am I right?
Another question: what kind of grammatical structure is this sentence?

THANKS.

No, he's saying something like "I've been a bit stupid for not realizing how upset you actually were, after hearing all the talk about you not being a member of the band group anymore."

In other words, he heard the rumors that Amy wasn't a part of the band, but didn't think they were true, because he didn't realize Amy was really upset about the situation.

Another question: what kind of grammatical structure is this sentence?

It's not a grammatical sentence, it's just a sentence fragment representing dialogue.

Thanks, Skrej.
Could I change the sentence into 'All that stuff about your not being in the band any more'?

'Being' would be a gerund instead of a participle if 'your' was used instead of 'you'.

You could, but it still wouldn't be a grammatical sentence. There's no main clause, so it lacks a subject and verb.

I think it is a noun phrase where 'about you(r) not being in the band any more' is an adjectival prepositional phrase modifying 'stuff'.
