assuming you've been cheated on is perfectly reasonable

I guess this proves the old saying, when you assume you make an ASS out of U and ME. If she had given him the benefit of the doubt, kept her mouth shut and waited on the secondary results, there would have been no damage done. But no, had to run her mouth to everyone immediately jump to conclusions after she had been with him a YEAR. A fucking Year of trust thrown away. By her overreacting. Talking shit and getting massive attention over some social media post too I'm sure. As others have said I wonder what the next over reaction will be about? I mean OP can forgive and move on but she has put this giant shit stain on the relationship now. Not that it's impossible to move on from here, but it's at least worth the OPs time to reconsider this woman being in his life. She threw him under the bus immediately. That's a character flaw. Not that those can;t be worked with but damn! a year of trust, gone!
