My husband seeks out other women. He has done so continuously over out 27 year marriage. I was oblivious at first but started joining the dots and saw a pattern starting to emerge. He always denies that anything has happened. The latest one is with a work colleague. He spends time with her after work, on weekends but says there is no sexual relationship, she has referred to him as his best friend. I don't understand why he doesn't just admit it.
