Any advice would be nice. 😊

So my fiancé is a very emotional guy and I'm not at all. He gets depressed about his job really easily and I never know what to say when he says that he's had a bad day. He says he wants me to show more emotion but that's just not who I am as a person. His mom raised him to wear his heart on his sleeve and I was raised the exact opposite and I have no idea how to "show emotion" like he's wanting and honestly I think it would be embarrassing and over the top if I did because I'm a super shy person. I'm scared that it's a fight waiting to happen because he's trying to pull something out of me that I don't have or can't find. And don't get me wrong, I know how to laugh and cry, but when someone tells me they've had a bad day almost every day of the week, I kind of run out of things to say. And he makes me feel like some kind of emotionless statue when he tells me that he wants me to be more emotional. I just wanted to get some opinions or advice. Do I need to learn to show emotion? Or is he not accepting of who I am?Â
