Basically, what I'm asking is: Have you felt like this? Did you do anything about it? Any words for someone who's feeling it?
Yeah, I've felt like that.
My words to you is to try to let go of past bitterness. Because the longer you hold on to it, the more you increase the risk of your suspicions towards this new girl to become a self-fulfilling prophecy.
I.e the more suspicious you are towards her and let that influence your behaviour, the more it will drive a wedge between you and most likely make her care less and less about betraying you since you're acting like a dick towards her for something she didn't even do (but some other girl did).
I'd also point out that you have to consider the rammifications of betrayal. I mean is the world going to end if your girlfriend betrays you, cheats on you or whatever? It will probably hurt, yes, but then what? It's not like it's gonna kill you is it?
And if the record showed that you gave the wrong person complete trust, what does that say about YOU and THAT PERSON? Sure, initially you might feel stupid for trusting someone who betrayed you, but stupidity is only proven by rash and immature decisions. A girlfriend or respective other is someone you're pretty much SUPPOSED to be able to trust, and if you don't then the relationship will have a definite expiration date.
So deciding to trust a lover isn't really about being a stupid/rash/immature decision at all, it's admitting the risk of being betrayed but deciding to risk it anyway because you genuinely believe the person you trust that much to be good enough to deserve that trust.
And if that trust turns out to have been misplaced, then it will say a lot more about the person who abused that trust, than it would ever say about you who were willing to risk being betrayed.
