Gisele was probably tired of fighting his real mistress (Football). It was pretty interesting to see the real intent when he compared football to military deployments, while partially true is not completely honest.

So she is a career woman who tabled her work for the family and now it was his turn and he failed to do so, and the fact he backed out of the agreement was probably the straw that broke the back in the relationship.

There are no records to beat or get and nothing left to prove.

Unless he wants to play until he is 50, which he may need to :)
