That's rough...but think of it this way if you yourself never betrayed the relationship your hands are clean... it's no fun being taken advantage of... But you get to move on when you're ready to and will have a clear mind and no extra baggage...

First off, if you feel compelled to go through someone's phone, they're not the one. I know that's a bit of an absolute and yeah, there can be some nuance to it in the sense of this scenario or that scenario, but ultimately, that's a major issue. Second, never move to a completely different place for someone you just started seeing. Doubt she'd do the same for you and why should she, you or anyone else? As a person who has been involved with someone who was cheating on their boyfriend with me, I can almost assure you that it's a her problem, not you, so don't internalize this (easier said than done, I know). Obviously everyone is different, but the person I was involved with for example is just incredibly -blam!-. She even said herself that no matter who she's with and how much that person loves her and treats her right, it's not enough. She's also someone who while being aware of a problem with herself, won't do a damn thing to try and change it. I don't know the sub human who cheated on you, but I'd bet my last dollar she has some underlying issues that need to be worked on. Idk though, maybe I'm completely wrong and it is a you problem 🤷🏽‍♂️ Go join a gym, pick up a new hobby (gym is not a hobby nor should it become your personality) and focus on yourself. It's trite, it's cliche, but you really should be healed from stuff like this before trying to get in another relationship.
