I agree. How old are they?
I'm also a little confused about the number of people involved here because you switch from plural to singular pretty much without warning. It's "two girls and two guys" and one point, but then there's you, and also but did the break happen between all four (five?) of you or just the two "lovers"?
I guess if you really wanted you could try to talk to them seperately and reason with them, or at least find out why they started to be so cold to eachother. Perhaps something happened that you don't know about. I guess you should try not to be too impatient about it, and just slowly work your way through their layers of defence. If there really is nothing to their ignoring eachother, then they will eventually realise this, though I don't think it'll ever be the same after such a long time.
Anyway, they're not talking and it doesn't look like it's gonna change, so why not just not put them together in a situation that you know will be awkward?
How ya doing, buddy?
