If....

IMHO the opening question has far too many unknowns. What sort of couple? How long were they together? Was their relationship doing okay, or were they already circling the drain? Do they have kids? Was it just one of them looking for a little sumthin' sumthin' or were they both wandering?

Furthermore, the way you phrase the question sounds false to me. The couple broke up because of the outsider? It doesn't actually work that way. A couple that has their relationship on a solid footing cannot be broken up by an intervening Lothario. There needs to be something already rotten at the core of the relationship, or at the core of one or both people.

Anyway. Ask again, but with way more specifics.

More important still, how hot is the girl?

As other people have said above...the bro code applies between friends...not strangers.
