I never jumped in on the whole "Gisele wants Tom to quit" thing...much too fraught with peril... But I just might here.
I have read/watched probably every interview Gisele has done since about 01' on...I even translate her interviews in other languages. The very first time someone ever got her to talk about Tom in an interview (08'I believe)she brought up that football was his passion. In 08' she had a Brazilian TV show ask about if Tom gets hurt, she said how he gets huge bruises & all banged up & she's like "Oh my God", but he's used to it & something to the effect that he knows how to take care of himself... In 12' she talked about how she understands that football is Tom's passion, how it "feeds his soul". Many of the interviews I do not have transcripts for, but you see a very clear picture of her feeling that Tom loves football,she may not understand football herself, but it is a crucial element to his happiness, so she fully supports it. She has talked for years about how each individual has to do what makes him or her truly happy, before they can make other people happy. I do not believe Gisele would try to make Tom quit if it's not what he wants. She can be an annoying holier-than-thou celeb at times, but the picture I have gotten of her over the years is that she is fiercely loyal,devoted, passionate, somewhat hotheaded (& occasionally regrets making comments after she sees them in print) & fanatically supportive of her family & friends ambitions. From saying she didn't find British men attractive back in 03, to saying Tom has concussions in 17', non story then, non-story now.
She always has & probably always will make comments without thinking about the effect they will have. Inherently a good person, runs her mouth at inopportune moments. Tom seems to really like her & everyone in the fashion industry has nothing but praise for her professionalism, work ethic & personality. She's human after all.
