You tell me?

my husband worked at this place for a year.this woman started working there all of a sudden he cant stop talking her up to me.tells me her entire life history>How he really likes her?How she reminds him so much of me?etc.then all of a sudden the phone starts ringing off the wall one of the guys from work/starts making 3-4 trips a night back into work to check on people./lies to his friend about going to midnight bingo so that he could leave the house without him alone.this went on for months.until his friend from work called our home animously left this woman's name with me.then no more phone calls/no more trips back into work/no more bingo/eveything that had been going on came to a complete stop at the drop of her name>What do you think was going on? Co-workers went to my family /friends said they were having affair.husband said it is all lies.Yet he did want to confront the people that he said were trying to destroy our marriage.
