Boyfriend says im disrespectful in certain settings F31 M31 i would love married couple insights?

My boyfriend M31 says i F31 embarrass him in public when it comes to men. We were at Home Depot looking at white paint swatches and a older guy comes up to us and says he painted a lot of houses with a certain white. I said oh really, and picked up the swatch to add to our collection. The guy then proceeds to talk to us about the colors and my boyfriend said because i maintained eye contact with the man that's usually an indication that i sleep around a lot and it's embarrassing to him and that's not how a wife should conduct herself. Today we met with a business partner of his who he told me to contact to set up our meeting, I've been calling the guy getting everything together for us. We go to his house and while him and my boyfriend are having a convo i look at my boyfriend a majority of the time or play with the dogs that are there. Occasionally during the convo the guy would try to make sure we both felt included in the conversation eventually they both sit on the sofa across from me and while they are talking i still try to mind my business as much as possible rarely ever saying a word or giving the guy any eye contact. Once we leave my boyfriend says my body language was too inviting and i should have been on my phone (that had no service) or i should have directed my body towards the wall. Is this what men expect of their wives? Because usually when he is having a conversation with guys even his own family members i walk out of the room or wherever i can go. In this case we were in the man's living room.
