I found out this past week that my husband has been having 2-4 hour conversations late at night with a female coworker. I started to worry and looked into his text messages. She sends him a good morning text every morning even though they will be at work together within the hour. I asked him about all the phone calls and the texts and his response was the texts were just because they were friends and the phone calls were because she's having problems in her marriage and needed to vent and wanted his advice. I'm pretty sure that he hasn't had any physical relationship with her, he doesn't work late and I talk to him throughout the day. But when we talked about it he said that he has also been divulging how he deals with similar issues in our marriage and that talking to her makes him feel good in a way. Should I worry?
