How much can we trust Fleabag's narrative?

I was wondering this too. Haven't finished the series yet so I want to see how it pans out.

Great question! I was wondering about this too, then decided we really don't have any reason to doubt Phoebe's narrative. I decided to believe her because

1) We don't have any examples of when she has misrepresented something, the worst she's done is omit things.

2) The brother in law has been shown to be not very scrupulous in general, like his loaded jokes, for example.

Hmm, I didn't doubt her view on the brother-in-law kiss, but I'm wondering if we will found out that Boo didn't die "accidentally" but committed suicide. Anytime someone brought up her death, FB was defensive about the accident part. If your best friend tells you she's going to do something stupid/dangerous, wouldn't you try to talk her out of it or at least talk her down. So from what we see, FB just lets her go forward with this awful plan?

FB feels guilty about being the cause of Boo's distress. I'm thinking she's telling us and herself that it was an accident to ease her guilt because she either A) didn't stop Boo's "accident" plan or B) it wasn't an accident
