My boyfriend can be a bit boring at times, and I'm not sure how to handle it. [I - 23F and BF - 24M]

I've been in a relationship with my boyfriend for three years, and we've been living together for the past year and a half. I'm 23, and he's 24. While I have a lively personality, he’s much more laid-back and seems uninterested in many things. The surprising part is that he’s a stand-up comedian and performs at local cafes. However, when we go out, he doesn’t show much interest or take on adventures like I expected when we started dating. I’m struggling to communicate to him that I thrive on excitement and want to live life to the fullest. For him, quality time means sitting together for dinner and watching episodes of Shark Tank, which feels a bit dull to me. He’s not into public displays of affection, even something as simple as holding hands, and he doesn’t share my love for dancing. When we're at concerts, he doesn't even look my way, and it’s puzzling. I truly want to marry him because he understands me in a way that no one else does, but this behavior is really putting a damper on things. Is it normal to feel this way? Or am I overreacting?
