I did a supremely dumbass thing and accused this girl I've been seeing of lieing to me. I just knew for sure I was right and had every reason in the world to believe I was right, but damn if if it didn't turn out that I was completely wrong. Bad luck I guess. I feel like a total dick. What should I say or do next? How do I appologize in a sincere and good way and try to repair thing? If anyone has any advice, I would really appreciate it. I don't know what to do after being such an idiot. Thanks
