This might come between us?

Hi,

What does the phrasal verb ‘come between us’ mean in the following conversation:

[i]A: Listen, I came across this old file template when I was looking for solution for our price lists. I showed it to Frank and he said it looked OK.

B: Oh yeah? I think this template might come between us.[/i]

Many thanks,
Torsten[YSaerTTEW443543]

Hi Torsten,

I’ll hazard an explanation - to me it suggests that it could cause a dispute between us.
