Ok, I have a few questions.
-So Littlefinger started the whole thing right? He got the Starks and Lannisters to kill/bankrupt themselves with a murder, and now wants to marry Sansa to what is perhaps his son? to secure the north for himself while having lordships in two key areas. Guy is crafty.
Knowing what we know now...
Who does Tywin think killed Jon Arryn then? It's a major move from someone outside his family.
Littlefinger is getting in deep.
Maybe Tywin doesn't know any more than anyone else, but perhaps he suspects Cersei, which would be natural for anyone knowing the family secret of her and Jaime, and perhaps that's one reason to back her to the point of war, and also perhaps he doesn't care as long as his heirs land on the throne, which they have.
All this perhaps Littlefinger could have counted on happening.
