Bit the shortened version is, the only way your account can get hacked is three ways, 1: you clicked on a trojan horse file and he stole your data. Which isn't cheap to run. And he would have to virus you to do so. 2: he pass-guessed your account, but he would have to have your email to do so. Or 3: he purchased a personal hack client to hack into your Google/email, just to enter your account. Which is nearly impossible given the fact Google does a good job against these, so it would take multiple clients of high quality to even get into your Google. All in all, the only way he could get in is if he trojan horsed you.
