Trust is a concept, condoms are a thing.

I understand you 100%, I dated a great, ambitious (studying to become an engineer for Mercedes), well-spoken, a gentlemen, the epitome of urban sophistication. He cheated on me once, he was honest about it, we're still friends and I wouldn't rule him out as a future lover if he moves back to my state and I trust he wouldn't cheat again, but him doing it once made me realize we're all human and even the best of us falter. Good people cheat too sometimes, all it takes is one moment of weakness, we're not Gods.
