Basically, I don't know how to trust anyone in my life anymore. Four years ago I had a girlfriend and towards the end of our relationship she had sex with my brother. I don't believe it gets much worse than that, I was a wreck. They both deny it to this day, but he has subtly admitted it because he is an idiot. I hold nothing against the two as I don't talk to the girl anymore, but I treat my brother the exact same, I will always have his back no matter how shady he is or whatever problems he has. Well four years later I have a girl friend and currently we have been together for 1.5 years, we are so happy and great together. I am slowly tearing us apart making a big deal out of nothing, she deserves my trust and is a great girl, but I feel like I don't even know how to anymore...Two people I really cared about just went and did that to me and I was devastated, vagcrew I need your help, I am into this girl!
