What my best friend said doesn't match up with what my girlfriend told me. I'm beginning to get suspicious, but I don't know who to trust. I've only been going out with her for 3 mos but I really really want to trust her. But then that makes me feel like I'm betraying my best friend. There's no signs of lying in either of them so I don't know who to believe. This is putting stress on me for 3 days now. It is putting stress on our conversations and relationships and they both hate each other and it has to end somehow. How am I going to resolve all this?
