DEAR ABBY: After 10 years of being with my wife, including eight years of marriage, I accidentally discovered she was having affairs online. She put me through weeks of lies, denial, minimizing and obfuscating before finally giving me full disclosure. At this point, I’ll never know if I can believe her after her seven years of off-and-on cheating with one main partner and two others. Even if I were to believe she’s remorseful and has changed, it’s hard to live with what’s already happened.
