Guys, sus or no?

My boyfriend is a repair technician, an has some designers he works with. half male half female. One of the females got his number and he usually list them under the company name and then their name. But this time, he named this contact design team, although it was the curly haired girl I thought it was (I used to work there) an he also put her notifications on mute. I see she texted him about painting something and unsure of the color and he stated let me know if she decides another color. I am hurt how he would be upset I texted a females coworker and Muted them I am annoyed he muted her only and named her only Team and not a group message
