Aaron Finch. He's an Australian cricketer bloke. I guess OP's girlfriend is an Aussie, so he uses finch as a mediator. And OP seems to be saying he'll dump the girlfriend if finch isn't allowed to mediate.
Ah, thank you! I did a quick search (just "finch") but nothing relevant was on the first page. "finch software" got me what I wanted (a few results down the page).
