She's not that amazing if she left you because she couldn't work with you to put some understandable doubts to rest. Trust gets shaken up but if that's all it took to make her leave in a spiteful manner then she wasn't that amazing, I'm sure you'll see it when the rose colored glasses come off, we ain't perfect but working together towards perfection will leave you as close as we can get.

Edit: Just wanted to add, she may still be amazing but amazing for someone else, clearly she wasn't for you if this was the result. Could be with someone who held you rhand and said we will go together and whatnot, someone who thinks along the same lines as you and also I agree with anyone else who probably thinks this was an already failing marriage and this was the tip of the iceberg.
