Guy's Behavior

Is my boyfriend embarrassed of me?

My boyfriend and I been together for 13 years. A really long time together and I think I know him well and so does he. Like normal couple we had are ups and downs but manage to keep a good relationship but there’s something that I’m confused about and starting to think he embarrassed of me.
Let me start by saying that we usually don’t go out and when we want to get away we usually get a hotel for the weekends. When we order food for delivery I notice that he tells me to move from bed ( facing the door ) or just simply “hide”. Usually I’m wearing shorts or nothing to revealing. Just this weekend I was chilling in bed with him when the delivery guy knock and he said move or go to the bathroom. I just moved out the way of sight and went to the bathroom to go use it but I felt like my heart sank. I felt like he embarrassed of me. Why else would he want hide me I mean is normal for a female to be chilling in a hotel room. I don’t know if this has anything to do but I’m a shy person and he is more outgoing and we usually don’t do social activities with people , only he does. Not sure why he does this all the time. Just last time I had to go to the hotel lobby to show my Id. ( usually he checks in ) and he insisted to just give him my id when I decided to go with him. He was all red when we was at the lobby. Almost if he was uncomfortable with me. I do get social anxiety but I think at this point he making it more obvious who’s the uncomfortable one. I feel bad because maybe I made him that way because I get anxiety but also I can’t blame myself for him trying hide me.
No I haven’t asked him why he does this I also don’t want hear a lie. He is not the time to communicate good
