Proposal

So I know my boyfriends about to propose sometime soon. I’m not completely sure when but I’m soo excited. However I’ve always had a hard time properly expressing my feelings. I’m terrified that when he does I won’t be freaking out and crying and jumping for joy like you typically see. I don’t know if it has something to do with my aspergers or what but I’m so nervous that I won’t react how everyone expects me to. Has anyone else ever had this fear? And if you’ve went through it how was it?
