Hey OP, instead of getting yourself down thinking about could haves, let's talk about what actually happened - out of all the people your wife had introduced to Tinkerbell over the years, every ex boyfriend, out of all of the guys Tinkerbell could have decided were good enough for her human, you were the one she chose, the one that she deemed good enough for your wife, better for her than every other man she had brought home before. All those other guys were judged and found lacking, but you? You passed the test. And that is something to be proud of.
