Cooking for boyfriend?!?

So I'm 22 and he's 25. We will soon be living together and I'm really nervous. I know how to clean very well so that's a PLUS lol I know how to cook certain things but not a lot of foods and that's the only reason I'm nervous?? Like will he like the foods I make ? Or should I make his favorite meals? Or try new things? Idk!! I know how to cook a lot of Mexican food cuz my mother is Mexican and she made me cook with her when I was like 3 😂anyways what should I do? Or buy? Or read?? Like outta 100 I'm like a 55%😐😐😐
