Sorry but you went way overboard with not trusting her. She had had enough. There's nothing you can do to try to "win her back". She's made up her mind. The more you come around and try to ask for forgiveness and another chance, the more she will want to run away from you. Just leave her alone. I know it'll be hard, but it is what it is. Maaaaaaaaybe she'll come around if you give her a lot of time to herself... but I highly doubt it. No one wants to be with someone who wants to constantly check their phone or emails and has no trust in their s/o. You said you did trust her, and you just wanted "clues" that something was wrong but I call BS. You just wanted to see what she and her guy pals were talking about. You didn't trust her. Period.
