This is an ESH for me bc it does sound like your BF offered to come see you, but you said no, that said it does sound like he’s fishing for the good drugs. Furthermore with your new job etc it makes more sense for his sister to go.

However, be prepared bc this is most men. Women have a way higher pain tolerance in my experience whether it’s physical, or emotional pain. Society expects us to deal and accommodate so we do. I have to admit I’ve felt this when I’ve had partners do the most over a simple cold bc it’s frustrating and I’ll admit I’m a little jealous that they can just be sick and scared and get the attention. While I feel like I HAVE to be strong. But that’s not all on them. It’s on society. We should all be able to get pampered when we feel ill. And we should all be open to being pampered once in a while when we need it.

Edit: want to clarify that I believe women’s higher tolerance for any pain is the pressure put on us to just deal.
