This has happened to be once, but it doesn't really matter who. Cheating isn't really something I tolerate when it comes the the people I'm dating.. lol.. With that said, though, I'm with someone right now who has cheated on me so I do give second chances, but it took me a long time to accept and forgive him. I did jokingly tell him that he'd barely live to regret cheating on me a second time though.
Anyway, I wasn't embarrassed that the person I dated cheated on me with another man. He had never told me what his sexual orientation was though. I don't think I know what it is now though, I've not really kept in touch with him as it happened a long time ago, when most of my relationships wasn't all that close to begin with. Maybe I'll see him during the 10 year reunion of my High School.
