Well... since the cheating part is your friend I think it would be best if you talked to him about the whole thing. That's what friends do. Let him know that you feel bad about that and that you are in a difficult situation. Show him the pictures so he sees that he can't deny it. Let everything go from there.
IMO it's never a good idea to come between two fires and it is also not up to you to decide how serious this thing is and I, personally, would keep out of it, except of the talk with my friend. |
