Emotional attachment

Brook • Mommy of 2 boys and 4 Beautiful angels

My husband is developing an emotional attachment to a female at work. They talk everyday at work and even on the phone if he is off. They both even go to their job site to see each other if one of them is off that day. It is even starting to effect their co workers how close they are to one another. Should I be getting worried that’s something maybe going on?
