I received a call stating that my husband is having an affair with a married coworker. I confronted him and he totally
Denied it. He talks about his job constantly, however he has never mentioned this person during our conversations.

Do you trust him? Who was the person that told you about this affair? Do you trust that person to be honest with you?

Then maybe he isn't having an affair then.Maybe that co-worker wants your hubby and he keeps turning her down and that makes her mad.Talk is cheap so do you have proof he is cheating? If you trust him 100% then you should have just brushed it off as someone being immature.If his attitude towards you haven't changed and you still having sex like before then I really don't think he's being unfaithful.

When I was obsessed with my work, I used to do nothing but talk about my work also. Too many people, view their own self worth though what job they do. And often can't separate home and work.

So who called and told you ?

Unless you have real proof, you really can't accuse him. It's possible that someone dislikes him and is just trying to stir some strife. However, it is possible that he is seeing someone.

For now, all you can do is quit accusing and keep your eyes and ears open in case something develops.
